Description
Circle Seal Controls Model 2220B-1MM Check Valve
Catalog literature: Check Valves Catalog.pdf
The Circle Seal Controls model 2220B-1MM Check Valve is a reliable design that combines the functional advantages and operating economies of perfect sealing with small package size for low pressure systems where flow rates are small.
Features & Benefits:
- Quick opening / positive closing: opening pressures as low as 0.1 PSIG
- Zero leakage: “bubble-tight” against back pressure
- No “chatter” or “hammer”: the pulsating action of shock waves and hammer is absorbed by the resilient o-ring, which insures cushioned, quiet closing.
