610 SERIES CHECK VALVE

Maximum Operating Pressure — 500 psi
Maximum Operating Temperature — 180°F
Seat Area Open Diameter — .297

Design Considerations

The 610 Series Piston 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. The 610 Series Check Valve maximum operating pressure of 500 psi covers a wide range of air and fluid applications. The 610 Check is a compact design and has a positive seal at very low back pressure or slight vacuum.
