自动空气的释放阀门

Automatic air release valve will discharge air when filling the pipeline, only water will make the S.S float to seal and close the valve avoiding blow-shut by high speed air discharge. The kinetic air valve will be opened when vacuum occur or draining the pipeline only. The valve is appropriate for: Expelling the air at high flow velocity during the initial filling of the system;Introducing air when the pipe drains, maintaining atmospheric pressures in the pipe, preventing collapse and cavitation damage to the conduits; Feature Full flow areaReliable operation reduces water hammer incidentsDischarges high air flow rates up to 160m3/hDramatically reduces the possibility of obstruction by debrisUnconditionally guaranteed floatsSpecial orifice design: combination of bronze and E.P.D.M. rubber, assures long-term maintenance free operationOne size orifice for a wide pressure range (up to 16 bar/230psi)Non clogging and self sealing balls for trouble free operationAll inner metal parts made of stainless steelWorking pressure range: 0.2-16 bar. (3-230 psi)Lightweight, small dimensions, simple and reliable structureMaintenance and trouble free operation under maximum working pressureVandalism protect by a metal casting body Operation The kinetic air valve has two modes of operation: Discharging of air at a high flow velocity when the conduit is being filled. When water arrives to the valve, the float rises up and closes the outlet.Introduction of air into the pipeline when the internal pressure is sub- atmospheric. The pressure difference forces the float to drop to opened position, allowing large volumes of air to flow into the pipe.
