s.150 – EFFECTIVE AIR VENT FOR LONG LASTING INSTALLATIONS

Air trapped in a pipeline can seriously affect system operation and efficiency; when air pockets sit in the pipes, a restriction of the flow occurs.  Movement of these air pockets can cause sudden changes in flow speed and when passing through a restriction in the pipeline, such as a control valve, usually result in surges or water hammer.  Exposure to air also accelerates the corrosion of the pipe material.  All these conditions can result in premature failure of the installation.

The s.150 air vent valve is the perfect solution when air exhaust is required. With 10 bar pressure, +110°C working temperature, the s150 effectively removes air from pipelines and can be used in waterlines, water transport lines, water storage tanks, air conditioning systems, etc...


s.150 key features:


- Sand blasted nickel plated brass body
- Float in polyethylene resin
- NBR O-ring
- ISO228 threads 3/8"-1"



COMPRESSION ENDS VALVES

Compression ends are highly reliable, quick to install and a much easier alternative than soldering.
Although the primary advantage of compression ends may seem to be in their ease of assembly – just slide the pipe into the valve end and tighten the nut - their real advantage is in their ease of disassembly, which facilitates ease of maintenance, cleaning and replacement.
Compression ends allow flexibility and can also be used on plastic pipe by utilizing plastic (non-metal) compression rings which are widely available at most hardware stores.
The RuB s28 and s30 valves with compression ends have many advantages.  Specifically designed with the versatile compression end configuration, s28 and s30 also offer the significant features of having their body, ball and stem, all made of DZR brass alloy in compliance with governmental regulations for valves handling drinking water.  Utilizing new technology, these valves feature the reliability and competitiveness of brass while being comparable to bronze in corrosion resistance.


s28 DZR full port 10 - 54 mm compression ends, hot forged brass ball valve,  design approved by Swedcert (S), Dezincification Resistant ADZ-T and ADZ-P brass approved to SBN-PFS 1983:2 and NR-BFS 1988:18 specifications.

NICKEL FREE


Worldwide health regulations are becoming more and more stringent regarding the presence of nickel in products in contact with drinking water. 
RuB has been responsive to these regulations and offers the following solutions to meet this growing need:
- Nickel plating is applied only on the outside of the valve so that it does not come in contact with water running    through the valve; yet is offers a nice metallic surface outlook.
- Nickel will be completely removed from ball plating in the dedicated “Potable Water” valve line, thanks to the new patented COPPER PLATING PROCESS that will also feature the advantages of the anti-bacterial properties of copper.
- Valve balls are featured with a rinse hole that prevents stagnation of water and helps preventing Legionella.
Scientific studies suggest that the use of copper in water installations is the most effective method for preventing Legionella bacteria and results in greater protection than installations made with steel or PEX materials.

This is another example of RuB promptly responding to the market needs!  Please ask your RuB sales person for further details.

s.468 for Activalve®


The newest product in RuB family is Activalve ®, which we started promoting recently and can be seen on the RuB website www.rubvalves.com 
Activalve ® has several unique features including the s.468 ball valve that is supplied as part of Activalve ® package.  

1- Low lead content: the brass alloy used to manufacture s.468 ball valves meets the lead free content requirements of USA regulations (Safe Drinking Water Act) in drinking water.
2- DZR: DeZincification-Resistant properties are enhanced by the combination with Low Lead and use components accepted in all EU countries where HCACL – UBA list - is in place.
3- Anti-freezing: s.468 valve is specially engineered to protect against freezing fluid inside the valve and is perfectly suited for the Activalve ® application.
4- Ease of installation: the valve features compression ends, in compliance with EN 1254-2, for quick and easy installation.

All details from material to configuration are carefully designed and engineered to provide you with the highest level of performance!

UBA LIST

The European four Member States (Germany, France, the United Kingdom and Holland) formalized an initiative in 2011 aimed at the convergence of the legislations of their own countries into one to ensure the hygienic safety of drinking water.
In addition, Portugal is now a Candidate Member, since planning to introduce a similar scheme following the 4MS Common approach. 
The 4MS intends to adopt common, or directly comparable, practices for:
- The acceptance of the constituents used in materials in contact with drinking water
- The testing of materials
- The use of common test methods and setting acceptance levels
- The specification of tests to be applied to products
- Review of factory production control and setting audit testing requirements
- Assessment of the capabilities of certification and testing bodies
A Joint Management Committee has been created to coordinate the activities of the representatives of the adhering countries in support of the initiative.

Tasks have been assigned to each state so that each is working on a specific type of materials: 
• Germany responsible for metallic materials. 
• Holland responsible for organic materials. 
• France responsible for cement materials.
• UK responsible for standards regarding microbiological and material growth and non-metallic materials. 

Metallic Materials - What’s UBA? What’s UBA list?
The Federal Environment Agency (Umweltbundesamt, UBA) is Germany’s central environmental authority. Established in 1974,  the Federal Environment Agency is a partner and point of contact in Germany for a number of international institutions, for instance the World Health Organization (WHO) and the European Environment Agency . 
Pursuant to the amended German Drinking Water Ordinance, since December 2012 UBA has been tasked with specifying mandatory evaluation criteria for materials and substances that come into contact with drinking water. The guidelines and recommendations issued previously by UBA were less legally binding. The new guidelines and recommendations will be implemented in the mandatory evaluation criteria in the coming years. 
Finally all the work of 4MS common approach was included in the last Revision (4th revision dated Jan. 20TH, 2015) of the document ‘ACCEPTANCE OF METALLIC MATERIAL USED FOR PRODUCTS IN CONTACT WITH DRINKING WATER, see: https://www.umweltbundesamt.de/en/topics/water/drinking-water/distributing-drinking-water/approval-harmonization-4ms-initiative. 
The document is divided into: 
Part A – with procedure for acceptance: The 4 MS have adopted Part A of this document as a common basis for implementing the concept of accepting metallic materials in their national regulations. This document is subject to revisions agreed by the 4MS.
Part B – 4MS   with Common Composition Lists  (https://www.umweltbundesamt.de/sites/default/files/medien/374/dokumente/150120_4ms_scheme_for_metallic_materials_part_b.pdf): this document includes a list of metallic material accepted in all of the 4MS following the procedure described in part A.

Which are the products affected by the UBA list:
Any product in contact with drinking water (wetted surface) including all products and components used in the water facilities for reservoir, treatment and distribution of the potable waters for human consumption.
Additional products include sanitary faucet products, valves, joints, tubes, pumps, water meters, filters, electrical and gas water heaters, solar boilers, heat pumps for the production of hot sanitary water, equipment for water treatment, etc.

Where does UBA list apply:
The adhering countries of the 4MS Group are responsible for the technical details of the work but it is important to stress the new regulations will become binding only after their implementation in the national legislative body of the individual adhering countries.    This process of integration has separate timelines in each of the adhering countries which are undetermined and difficult to predict at this time.
The UBA list is currently in force in Germany.

RuB is – to the best to its knowledge - strictly following all regulations and rules in all countries and will continue to monitor situations as they develop in different countries.  RuB is offering products made of brass alloys that are UBA list compliant.
