Double chamber VS-4 Smartvalve advantages
STAGE 1I. Air and water enter the VS-4
Smartvalve.II. Only filtered water reaches
the float assembly.III. Valve is closed: rubbish is
confined in the cylindrical filter.
IV. Valve is ready for more air.
STAGE 2I. When more air enters, it
first displaces the water and contaminants downward and back to the main.
II. This primary air compression chamber holds air at all times for best anti-hammer and shock control.
III. The two stage seals maintain correct valve operation at all times unhindered by solid contaminants.
STAGE 3 I. At times of negative
pressure, the primary compression chamber helps expel rubbish back to the mains.
Reduced MaintenanceWith its tubular �ne mesh screen, solids are excluded from the �oat and seal chamber.
Cost SavingsReducing short and long term maintenance costs are an important consideration. By virtue of VS-4 Smartvalve’s anti-hammer design, pipe fatigue is greatly reduced. Smartvalve guarantees an anti-slam pressure chamber of air at all times.
All things considered, VS-4 SMARTVALVE Is the smarter choice!
The VS-4 Smartvalve overcomes previously experienced faults found in all single chamber valves (see page 2 Comparisons).

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.
The VS-4-PW air valve is not suitable for sewer mains as it is liable to clog with solids as happens to other single chamber air valves. For contaminated mains please refer to the ‘Double Chamber’ VS-4 range.
