Product Description

Compact water design extremely light weight and economical compared with traditional flanged type, swing-check valve. 

The sensitive spring incorporated in the valve closes the valve plate before reverse flow occurs preventing water hammer and giving complete pipe line protection even in the high head installations. 

Space saving design simplifies installation. NSSL dual-check valves can be installed in any position and at an angle allowing rationalized piping layout. NSSL dual-check valves incorporate teflon spring bearings to minimize spring wear and assure long service life. Teflon bearings minimize friction for smooth valve plate operation. Shock-easening and tight sealing effect ensured by resilient seat.
