Automatic air vent valves for hot and cold water distribution systems
Purges air that may be in the water system and utilizes a float to actuate the valve plug which is located at the top of the valve.once the air is displaced and the system pressure is sustained,the valve plug seals and prevents any water from escaping from escaping from the system.the float vent can also operateas an anti-vacuum device,since it will permit air to enter the system when it must be drained.it can also be installed to permit the separation and dispersal of air,while fluid is actually circulating in the system.
