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
