VS-4 Combination Air Release Valve

History and Rationale
Odour Technologies have looked at the problems experienced by wastewater operators with air release valves. Over a period of 5 years we have designed and tested our double chamber valve that overcomes previously experienced faults found in single chamber valves.

Reduced Maintenance
Due to its ability to work maintenance-free for extended periods, it continually maintains and protects itself from the rigours of wastewater transfer, the name “VS-4 Smartvalve” was an obvious choice.

Cost Savings
Reducing short and long term maintenance costs are an important consideration. By virtue of Smartvalve’s  anti-hammer design, pipe fatigue is greatly reduced. VS-4 Smartvalve guarantees an anti-slam pressure chamber of air at all times.

VS-4 SMARTVALVE Combination Air Release Valve

FEATURES

VS-4-PW for potable and non solids contaminated waters. 316 stainless steel. PN 16. All VS-4 models are CE certified. Spin on or flanged to suit customer requirements. Seals at atmospheric pressure and rated to 16 Bar. This is a combination air valve with built-in anti-slam and anti hammer. All parts are rated food safe. The Standard orifice is 1160mm2 and a super high flow model is available to order with a 2826mm2 orifice. Water and air flow are horizontal to the float base to stop premature closing. There is also a screen to stop fish, frogs, eels etc from entering the valve chamber. This potable water valve is bred from the extremely reliable VS-4 range of sewer trunk main valves.

SPECIFICATIONS

  • The VS-4 SMARTVALVE is constructed using 316 stainless steel and fully pickled.
  • A full service can be done from above, on-site, in 5-10 minutes. No heavy lifting in and out of pits.
  • The primary chamber is sealed and cannot lose its air charge thus maintaining anti-hammer properties continuously helping to protect the mains.
  • The tubular screen in the primary chamber prevents rubbish entering the secondary chamber thus protecting the valve assembly.
  • The 2kg (4.4lbs) positive buoyancy of the float seats the seals at atmospheric pressure. Rated at 18 bar.
  • On vacuum type mains a one-way-only valve can be fitted.
  • To double or treble air flows the VS-4 SMARTVALVE can be ordered with a second or third valve chamber attached to the primary chamber.
  • The base flange is a table D 4 inch with adaptor plates for all other sizes. Special base flanges can be ordered to suit customer requirements.
  • When compared to single chamber valves the VS-4 SMARTVALVE service interval can be extended by up to ten times.
