Inline Poppet Check Valve

Specially designed poppets for hyper compressor lubrication systems, initiator delivery lines and reactor entry points.

KMT’s new poppet check valve was designed to address the “hot check” problem common to many hyper compressor lubrication systems. Other applications include initiator delivery lines and reactor entry points.

The new valve offers a larger contact surface, which provides a more positive seal while resisting the inclination to brinell at the point of contact.

The new internal design positions the spring around the outside diameter of the poppet guide. This provides the spring with extra support while allowing flow to move around and not through the spring.

The use of 15-5PH stainless steel material for the bodies, seat, and poppet guide provide excellent resistance to fatigue, corrosion, and fluid contamination. Extensive testing indicates this combination extends the service life 4 – 10 times over that of a conventional ball and seat design.

Inlet and outlet connections are available in standard 9/16” and 3/8” HP sizes. Special connection designs are available upon request.

Design Criteria: 60 GPH (227 l/hr) @ 60,000 PSIG (4138 Bar)
