The 410 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. This valve has a 1/4"MNPT inlet and a 1/4"FNPT outlet. Valve body is .69" diameter and 1.63" long.
