Available in a wide range of sizes and cracking pressures, our mechanical check valves can handle up to 6,000 psi and temperatures up to 600°F. Common applications include pharmaceutical , life support, and oil & gas. We maintain a large inventory of instrument check valves, including welded check valves, compact check valves, ball check

15. Fixed Cracking Pressures. From 1/3 to 25 psi (0 .03 to 1 .8 bar). Adjustable Cracking Pressures. From 3 to 600 psi (0 .21 to 41 .4 bar). O-ring seals.

They are used in combination with piston, diaphragm and metering pumps and commonly use ball check valves that combine balls and seats in the same valve body for a leak-free shutoff. Max.

The Universal Low Pressure (U3, UR) threaded check valve is a one-piece body machined from bar stock and is designed for minimum pressure drop. The valve is light-weight, compact, and provides maintenance-free dependable service. NPT threads are per ASME B1.20.1 and this valve is also available with ISO 7 “Rp” threads (UR).

Parker’s MAC Series (Ball and O-Ring) Check Valves provide unidirectional flow and shut-off for liquids and gases in medium pressure systems up to 15,000 PSI. These check valves utilize

Pressure-Relieving AirCompressor Air Flow Check Valves. Release pressure in the line between a compressor and an air storage tank, making start-up easier on the motor. These valves open to allow flow into the tank and close when flow stops or reverses direction, preventing air from escaping the tank when the air compressor is not running.
