VS-4 SMART VALVE

The VS-4 Double Chamber Smart Air Release Valve Advantage

Odour Technologies have looked at the problems experienced by wastewater operators with air release valves. Over a period of 15 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.

Single Chamber Air Valve Faults

  • By their design, single chamber air valves are very prone to blocking.
  • There is contact between contaminants and float and seal assemblies. The float rises, the air compresses and contaminants rise above the float where it then accumulates as a bird nest of cotton buds, fats and other items.
  • It is very common for seals in a dirty environment to leak small amounts of air. When this happens the floating detritus accesses the valve seal assembly and causes total failure.
  • When conical and similar shaped air valves become blocked with fats and other solids it is very hard for operators to clean them making total removal to a workshop a necessity.
  • A blocked air valve with no air internally has no anti-hammer properties thus putting the mains under duress and prone to bursting.
  • Cast iron air valves are prone to corrosion.
  • Violent bursts of air or water in direct contact with the float assembly has a very destructive effect on the sealing mechanism.

The VS-4 SMARTVALVE Solution

  • The VS-4 SMARTVALVE is constructed using 316 stainless steel and fully passivated
  • 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.
