Liquid Controls - A2821 - 0651 Valve, Air Check, K7

Liquid Controls Air Actuated/Differential Check Valves are designed to prevent flow whenever air or vapor is present, thereby assuring accurate measurement.

Check Valves are normally closed, spring loaded valves installed on the meter outlet. When fluid enters the valve from the inlet side, and the pressure is greater than the back pressure combined with the force of the spring, the spring will compress, opening the valve and allowing fluid to pass through.

When back pressure plus spring strength is greater than the fluid pressure entering the meter, the valve will remain closed.

These meters are used in conjunction with the air/vapor eliminator to prevent air/vapor from being metered. This is important when split compartment testing.
