When your piping system requires pump and compressor protection, specify the Noz-Chek® high peformance, non-slam check valve.


This valve minimizes the damaging effects of water hammer in fluid systems and eliminates valve chatter associated with conventional valves in reciprocating compressor service. The flow area is designed to provide minimal pressure drop across the valve. Noz-Chek valves provide a quick dynamic response, reducing reverse velocity.


Sizes available are 2" to 84", in pressure classes 150 up to 4500, API 6A pressure classes 2,000 -15,000, in flanged or butt-weld ends.
