Is RuB a solid company ?

Absolutely! The company invests in our future, by paying attention to main trading issues, techniques for continuous improvement and prudent financial management. The dividends are constantly reinvested in new technology not only in production but for each department. The use of third party financing is extremely limited. The company has a large stocks around the world, which helps to manage the market oscillations.

Where is the company plant?

RuB offers its customers a 100% made in Italy product. The production plant is in the province of Brescia on the main road  between  Brescia and  Desenzano, in a town called Mazzano. There has been the  necessity to open two stock houses located in USA and in Japan to better serve  these two markets.

Are we sure they are quality products?

All our valves are submitted to strict project validation tests, test lines at each production stage, controls on material acceptance and each valves is submitted to an automatic dual seal test at 100%*. They are approved for water and gas applications by different certification boards all over the world:
– RoHS Compliance (EU)
– The Australian Gas Association (Australia)
– Canadian standards Association (United States, Canada)
– Underwriters Laboratories (United States, Canada)
– CSA International for Drinking Water to NSF/ANSI 61-NSF/ANSI 372 (United States, Canada)
– DVGW (Germany)
– DIN-DVGW (Germany)
– Factory Mutual (United States)
– SVGW (Switzerland)
– Kiwa-Swedcert (Sweden)
– Water Regulations Advisory Scheme (United Kingdom)
– Attestation de Conformité Sanitaire (France)
– GOST-R (Russian Federation)
– Hygene and Epidemic Center in Moscow city (Russian Federation)
– British Standards Institution (United Kingdom)
From Iceland to New Zealand, our valves are known as synonym of quality!
In addition, the company is ISO 9001 certified by Lloyd’s Register Quality Assurance in accordance to the PED regulations for pressurized vessels and regulations relating to safety and environment.
On average, in our plant we make 400.000 inspections/tests/verifications every day.
RuB products are warranted for two years.

* not all valves are suitable to a dual test sealing.

I’ve read in your catalogue that you sell full port valves and 100% full port. What is the difference?

The regulation DIN 3357 part 4 indicates that full port valves are those whose effective diameter is not less than a set, prescribed value in comparison to the nominal port: for example, a valve with 50mm port (2”) is defined full port if its diameter is not less than 47mm, a valve with 25mm port (1”) is defined full port if its diameter is not less than 24mm, and so on. The valves on which we indicate 100% full port have a ball bore perfectly identical to the nominal diameter of the pipe, so for a 2” valve, the effective port is 50mm.

What kind of material do you use for your valves ?

RuB is a specialist of brass manufacturing. All our valves components and materials are tested according to very strict quality standards. Brass is in compliance with EN 12165 and EN 12164 available also in various alloys depending on application and destination: CW617N, CW602N, CW510L.
For CW617N, RuB specifies that Pb contents should be lower than 2,2% for many years. This requirement will soon become a European regulation.
CW602N is a dezincification resistant brass alloy for hard water use.
CW510L is a brass whose Pb content is less than 0,25% and that is commonly called Lead-Free due to these percentage, the Pb content can be assimilated to impurity.
The ball joints are in virgin PTFE, pure or charged with various contents according to needs.

The stem sealing is achieved thanks to a dual O-ring in various elastomers, i.e FPM (Viton® is a registered brand Dupont), EPDM, or as an alternative, with PTFE packing gland seal.

The handle is made of steel  DD11 with suitable thickness,  able to support workloads higher than normal effort for the valve operating; Geomet® treatment that makes it three times more resistant to corrosion compared to normal  galvanizing  treatments; at the end, it is covered by a thick PVC coating that creates a thermic and electrical isolation and makes the handle more comfortable to grip.

Our valves are conform to European directive RoHS.

RuB can also supply on demand product in aluminum and in steel.

What kind of gas or fluids can I use with your valves?

The combustible gases are divided in families: methane, propane, ethane and butane. RuB valves are homologated for use of gases belonging to all families. Our valves are also compatible with many other fluids and in the website download section you can find a specific document with a multitude of data according to this.

Do you also have products suitable for drinking water use?

Each country has its own concept of “drinking water”. In many countries, RuB valves are suitable for drinking water use, however RuB has also developed valves in special alloys such as s24, s28, s21, s20, s26 made in DZR brass (CW602N) or S292 and the s242 in “Lead-Free” brass (CW510L) prescribed in certain geographical areas.

Do you produce valves that can be used for both water and gas application?

Even in this case, the answer depends on the legislation in force in the area in where the valves will be installed. Not all countries prescribe homologations for check valves with water and/or  gas use. Till today, we have several products approved by certification bodies for both water and gas use. e.g.:
-s84E and k84 are homologated  DVGW for gas use and KTW for drinking water use in Germany

In your catalogue I can’t find the configuration I need: could you help me?

YES. Beyond  standard production on catalogue, RuB has a large experience in customized products. The peculiarity of such products can refer to a marginal detail such as handle color, rather than requiring forges and  ad hoc equipment in order to combine more functions in same product. In this context, RuB supplies important markets such as automotive, heating, pneumatics, mining, water treatment, firefighting, tools machinery construction and more others.

Why does RuB manufacturing make the difference compared to competitors?

Our company is specialized in ball valve design and manufacturing and throughout the years we have focused investments in optimization of production process and in range variety.
The fact that the material received has passed all tests in BONOMI INDUSTRIES gives an intrinsic guarantee on the product quality, reliability and duration.
Our quality is determined by certified raw material choice, by strict working tolerances, continuous tests for product improvement that, even if simple, aims to great variety of applications with wide range of pressures and temperatures.
RuB valves are super performing for some applications but they are necessary if reliability throughout time is an important prerogative request.
Some features of our valves:
–  pure and virgin PTFE that assures better performances throughout time and use in the most extreme outdoor conditions;
–  they are silicon free and this makes them suitable for automotive applications and for any use with paint;
–  All project validation tests require a 25.000 cycles (open/shut, hence 50.000 maneuvers) test without leakages and blowout tests with large security factors;
– 100% dual seal test* performed on each valve for 24h with air pressure that highlights also the most little leakages!

* not all valves are suitable to a dual test sealing.

Can I purchase directly?

As manufacturer, RuB  establishes relationships with distributors covering a certain market or geography. They aren’t exclusive, but RuB  offers support to its distributors helping them grow sales and increase brand awareness. In particular cases, it’s possible to create a direct commercial channel but only according to certain terms.

How to recognize cloned RuB valves?

RuB has grown in the past thirty years to be an important player in the world valve business. The route was not easy and has required major investments in machineries, equipment, logistics, people and a serious commitment to continued improved quality. We are certified to ISO 9001:2008 by Lloyd’s Register and further efforts were made to comply with latest regulations in Europe (PED) and around the world. Along with this, new products are being developed and our catalogue continues to become reacher to help you increase your business and reliability in the valve industry.

Regretfully, there are areas in the world, where business ethic has different values and it is no news that manufacturers in the Far East have copied famous brands. RuB is among those being copied. Copies of RuB valves have been exhibited at shows and some products were distributed. RuB has already taken legal actions against manufacturers in the Far East and is currently prosecuting importers of false products.

RuB owns registered trademarks and logos that will actively and legally protect.

It is also in your own interest, that any information about copies of RuB valves is brought to our attention with names, dates, etc. It is our firm commitment to fight unfair competition in any possible way and those who will actively show their support to RuB, will be awarded.

We are worried for our brand awareness but we are much more worried for our customers! If our customers install in their system a valve believing it is produced in Italy while it is in fact produced in the Far East, and this valve is unable to stand pressure or doesn’t meet proper standards of quality, they could put at risk the entire system!

We anticipate our gratitude for your cooperation in this issue, we fight this curse but we need also your help!

As it has already occurred in the past, clones of RuB valves are being offered on the market once more, nevertheless those are completely unrelated to our company and production range.

We hereby inform you that:

– None of our product lines has been lately discontinued,

RuB produces on a regular basis its complete range,

– No change in series designation has been made,

– No production move out of Italy has ever been planned,

– Our products are of 100% Italian origin, produced in our plant in Mazzano (BS) Italy with state of the art equipment and processes and going through our unique 100% 24h seal test*!
Any letter, fax, e-mail or whatever written or verbal communication released by anyone giving contrary in- formation, is false and we reserve the right to take legal action against it.

We continue producing and dispatching our products in five continents and we ask you to please contact us in case you face any trouble in sourcing our products through your traditional channels. Through the years RuB improved the service and shortened lead times for direct shipments from Italy; an extensive network of professional distributors has been built to meet local stringent requirements.

Valves with design SIMILAR to RuB may not assure you the performances you are used to, that are granted through the years of experience and continuous improvement. Quality of ball valves depends upon engineering, extensive testing, choice of materials, tight tolerances, cleanliness, reliable inline tests.
Obviously, RuB cannot be held responsible for damages caused by products which are not made by RuB! In the attachment you can find a few tips to visually recognize the true RuB products, despite other valves may have similar levers and/or similar body design.
