Provides automatic air venting for (hydronic) hot or cold water distribution systems. These vents purge air that may be in the water system. The vent valve 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 the system. Brass body and cover with rubber seal. High temperature resistant. Suitable for use with glycol systems. Can be disassembled for inspection and cleaning. Minimum working pressure 1.45 P.S.I.; maximum working pressure 150 P.S.I. Temperature range 33 deg. F. to 240 deg. F. 1/8".
