G 1 1/4 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 21.38 m3/h (356 l/min @1 bar pressure). In imperial units: Cv = 24.72 GPM @ 1 psi pressure.

Description

G 1 1/4 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 21.38 m3/h (356 l/min @1 bar pressure). In imperial units: Cv = 24.72 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 alcohol

Cons:

  • NBR is unsuitable for brake fluid and polar solvents. EPDM or FKM are suitable alternatives in this case

Check valve series

The RE-GE series are removable and monobloque (only up to 2'') check valves made of brass. They are available with connection sizes from G 1/2  inch up to 4 inch. Brass check valves are a cost-effective solution for neutral fluids, such as water, oils or air.
