ACTUATION RANGE

With RuB’s top quality range of brass ball valves, for actuation and ancillary actuators, your operations canprofit from the following benefits:

-  A One Stop Advantage - The ability to offer your customers a complete service, with ready-to-use actuators, sourced from a single vendor.

-  A Competitive Edge - Now you can propose the innovation of small size ball valves for actuation.  Even hard to find sizes such as 1/4" and 3/8” are available through RuB.

-  A Wide Selection Of Choices – RuB lets you propose an interesting choice to your customers: Pneumatic or Electric Actuation.  We provide solutions for both types of actuation.  Your customers will not need to “look around” for alternatives!

In fact, the following RuB ball valves:

-       s.31 (Mini valve from 1/4" thru 3/4")

-       s.64/s.64LT (2-way, from  1/2’’  thru 2’’; options up to 4’’ available)

-       s.74 (3-way diverting, from 1/2’’  thru 1’’)

are specifically designed for use in actuation, ranging from ¼’’ thru 2’’.  They are available for direct mounting onto our CP-Compact Power electric actuator, as well as any ISO arranged actuator.

RuB’s CP-Compact Power series is an effective solution, you can propose, when only electric power is available.  Thanks to CP’s compact size, it is a practical tool for those times when actuation must fit in a confined space.  It fits RuB ball valves up to size 1.1/4”, and is available with 230 VAC, 110 VAC, 24VAC voltage ratings, and an IP rating of 65.

PNEUMATIC ACTUATOR EA

RuB’s EA series of pneumatic actuators for 1/4" - 2’’ quarter turn valves, have an ISO5211 direct mount on the valves, and are applicable for both indoor and outdoor applications. Thanks to optimized technical features, the EA actuators offer effective and long lasting performance. 

ELECTRIC ACTUATOR CT

RuB’s CT Electric Actuator is a first-rate actuator solution for 1/4" - 2’’ quarter turn valves with ISO5211 direct mounts. Contained in fire resistant plastic housing, it comes in several voltage ratings: 230V AC, 110V AC, 24V AC, 24V DC, 12V DC.

WHAT IS Cv (Kv) AND HOW IT USED

What is Cv vs. and what is Kv:

-  A Cv Flow Coefficient specifies the volume of water (in US gpm at 60°F/15.55°C) that will flow through a valve with a 1.0 PSI pressure drop across the valve.

     Thus a Cv Flow Coefficient of 10 indicates that a 1.0 PSI pressure drop will occur with a flow of 10 US gpm of water through the valve.

-  A Kv Flow Coefficient specifies the volume of water in m³/hour at 68 °F/20°C that will flow through a valve with a 1.0 bar pressure drop across the valve.

     Thus a Kv Flow Coefficient of 10 indicates that a 1.0 bar pressure drop will occur with a flow of 10m³/hour of water through the valve.

The difference between the two is only the system in which they are calculated, respectively imperial for the Cv and metric for the Kv. Therefore you can convert Kv into Cv and vice-versa using the following formula:   K_v = 0,865 C_v

The Flow Coefficient is normally used to size valves in a plant.  Once flow rate and pressure lost are known, Cv is calculated (or easily found in the technical datasheets) and based on that value, the most appropriate DN valve size can then be identified.  Simply, you need a big enough hole in the ball for media to flow through. If the hole is too small, the pressure will drop.  If the hole is too big, pressure loss will also take place.  Additionally, this means that you have overspent on a larger size valve than was necessary, and you’ve wasted some money (which will not make your boss happy…).

For further clarification or additional information, or to develop special OEM products custom sized to your plant’s pressure specifications, our Engineering department would be pleased to assist.

To whom it may concern

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 Ciliverghe di 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.

A complete overview of our production range can be seen in our official website: www.rubvalves.com

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! 

Here a few tips to visually recognize the true RuB products, despite other valves may have similar levers and/or similar body design:

RuB COMPATIBILITY Table

RuB COMPATIBILITY Table:

 one useful  instrument to support your customers from A (as Acetaldehyde) till Z (as Zinc Sulfate!)

We are quite often asked about specific applications by our customers, questioning whether our valves are suitable for a certain use. The answer is sometime very easy to give according to our knowledge and experience, 

provided the question is very clear and the fluid, working/ambient temperature and working pressure as well as any specific information related to the application is noted.

For example, it’s clear that a brass ball valve can be suitable for certain use at 50°C while it cannot be at 300°C, or it can be used with 6 bar, while it can be perhaps  risky to use it at 50 bars; therefore, when asking about application suitability, temperature and pressure always have to be taken into consideration.

Provided  temperature and pressure rates are kept as indicated in the relevant datasheet, then of course the main topic is the fluid, which might also influence the pressure rating and temperature range.

The list of fluids that can pass through a ball valve is indeed extensive, and your customer may even use valves for an application you wouldn’t have ever thought about…    

In this case, the RuB compatibility table supports you by showing whether the materials used in the ball valves are compatible with the specific fluid: the table shows the rating of each material, with evaluation ranging from  ‘excellent (compatibility)’ to ‘do not use’.

To get the Compatibility Chart, please click here (link to compatibility chart, alternatively  ‘Contact your RuB Area Manager’)

In any case, for any very specific – special – unusual application,  we also suggest that you check the valves on field. Our Area Managers will be pleased to support you on this.

S.31 mini ball valves for actuation

FOCUS ON: S.31 mini ball valves for actuation

As  you are certainly aware of, RuB recently introduced the s.31 mini ball valves for actuation in the production range.

S.31 mini ball valves are available from ¼” to ¾” with BSP, NPT and BSPT threads; with  a very compact design, they can be assembled in very narrow spaces and are sold at a very competitive price.

The s.31 minis can be very easily assembled on the COMPACT POWER mini actuator, it only takes a couple of seconds to click the valve to the actuator and to secure it with a spring (video to be added).

Now, thanks to an adapter flange, the mini ball valves can also be installed onto any other actuator having flange F03 according to ISO 5211:

(mini ball valves s.31 with adaptor flange to EA actuator with ISO 5211 F03 flange)

In addition to that, we are pleased to inform that our s.31 minis very recently received WRAS approval for drinking water!

What else should you expect from a mini ball valve for actuation? Please contact your Area Manager to get a quote!
