CHECK VALVES

CHECK VALVES

Body and Cover

Bodies and covers are high quality cast and afterwards precisely machined, directing the attention to prevent stress concentration.
The design characteristic of check valves is the unobstructed passageway, with a full-opening when required.

 

Body and Cover Gasket

The design of the body/cover gasket varies depending on the class of the valve.
Class 150 to 600 check valves consist of a male-female connection with a graphite or spiral wound gasket.
Class 900 and above check valves consist of a ring type joint.
In pressure seal designs the sealing is achieved through a gasket that takes advantage of the internal pressure of the line. The material most commonly used is high purity graphite being located between the body and the body retainer ring.
