SMC 215 Series 1/8" Brass Check Valves

The 215 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 flow arrow on the body will point from inlet to outlet.
