Zero Velocity Valve

Spring loaded self-actuated Zero Velocity Valve to prevent reversal / return of water column by perfect non-slam closing just before reversal of water column giving most effective surge control.

Air Cushion Valves

• Application : Self actuating Air Cushion valve for vacuum breaking. Dampens slamming of returning water column by controlled release of air for effective control surges arising due to tripping of pumps in raw water/clear water cross country rising main and lift irrigation schemes.
• Standard : JASH / SURESEAL.
• Mounting : Flange mounted.
• Sizes : 100,150,200,300,400 mm dia
• Actuation : Self-actuating
• Pressure Class : 10, 15, 20, 25 and 30 kg/cm2 (Hydrostatic body test Pressure). Higher class offered on request.
• Sealing : Metal – resilient
• Leakage Performance : Leak tight.
• Material Of Constrction : MS fabricated.
