Collection:Orifice Check Valves With Push-In Fittings

These valves provide fixed flow control in one direction while allowing the free flow in the opposite direction. They consist of a pipe which has a diaphragm check valve with an orifice in it. The orifice is effective in one direction while in the opposite direction the check valve opens and allows a free air flow. The valve has a push-in fitting, to connect a tube, on one side and a threaded fitting, to connect it to an actuator or a cylinder, on the other side.

The orientation of the check valve within it dictates which flow is metered. If the flow is metered entering a cylinder it is a meter-in valve and if it is metered exiting the valve it is a meter-out valve.

The push-in fitting sizes range from 4 to 8 mm and threaded nipples sizes range from R1/8 to R1/4 inch. You can choose from 18 different orifice sizes ranging from 0.3 to 2.0 mm. Two different models of constant flow speed controllers are straight and elbow (90 degrees).

Use the chart in the datasheet to determine which orifice size suits your application the most or call Tameson support.
