Design Considerations

The 815 Check Valve incorporates a piston with an embedded o-ring that seals on the seat.

Pressure in the flow direction moves the piston and seal off the seat and exposes the cross holes in the piston.

Maximum Operating Pressure of 500 psi covers a wide range of air and fluid applications.

Positive seal at very low back pressure or slight vacuum.
