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. Check valves have a maximum operating pressure of 500 psi covers a wide range of air and fluid applications. They are a compact design and have a positive seal at very low back pressure or slight vacuum. The flow arrow on the body will point from inlet to outlet. This check valve has a 3/8"FNPT inlet and a 3/8"MNPT outlet. The body is .87" diameter and 1.69" long.
