G 1 1/2 inch check valve made of brass with an NBR seal. The minimum differential pressure across the non-return valve must be higher than 0.04 bar (0.58 psi). The valve has a spring to close the valve when the flow is below the minimum pressure and to prevent backflow. The maximum operating pressure is 18 bar (261 psi). The operating temperature depends on the media: -20° C to +100° C (-4° F to 212° F) for air, -20° C to +60° C (-4° F to 140° F) for gas, and 0° C to +100° C (32° F to 212° F) for water. The Kv-value is 31.63 m3/h (527 l/min @1 bar pressure). In imperial units: Cv = 36.56 GPM @ 1 psi pressure.

Pros:
* Suitable for neutral and non-corrosive media
* Cost effective but reliable check valve
* NBR can be used with water, air, oil, solvents and alcoho
