Piston valve

manualfor airpipe

This valve has been designed for an efficient discharge of large air volumes from small water network systems, filters, containers and other devices where trapped air may impair the systems operation. The valve is appropriate for: Expelling the air at high flow velocity during the initial filling of the systems. Introducing air when the pipe drains, maintaining atmospheric pressure in the pipe, preventing collapse and cavitations’ damage to the conduits. Relieving the entrained air from the water while the network is pressurized.
