The AWH Ven and Exhaust Valve is integrated with a low density moving ball which serves as its control element. This ball is capable of operating like a ball check valve. It floats and presses against the upper valve seat as the liquid rises. Whenever the liquid level drops, the gas flows out to past the ball averting vacuums while releasing the system.
The valve's function is identified through the exchangeable lower valve body. The exhaust valve's control element is also a moving ball which works like a double-seat valve. It can be utilized in various applications like venting pump suction lines and pipelines. As its pressure tones down, the ball falls back to the lower sealing seat which averts the air from being sucked.
