Breathing Exhaust Valve

The vent valve is a reliable automatic venting valve that removes air as needed and is mounted vertically on top of the pipe or vessel.
The following is an example of the use of an exhaust valve:
Shown 1: Due to material or process requirements, the canisters form cavitation and therefore require air to be
vented. In this case, the valve is mounted on the top of the container.
●Specifications: 1"-12", DN25-DN200
●Material: ASTM 304/1.4301, 316L1.4404
● Washer: EPDM FPM
● Pressure: 10bar
● Temperature: -10 ° C to 130 ° C

Application
Exhaust valve is a reliable automatic exhaust valve, on-demand to clear the air, mounted vertically on top of the pipe or vessel, or at the inlet of the pump at the installation.
Here below are two examples of aplications.
Example 1:Air cavity is formed due to the installation of the pipeline, and thus need to release air. In this case the valve is installed at the top of the pipe.
Example 2:Discharge air at inside of the pipeline of the pump. When the pump opened the air will be automatically discharged and forming a vacuum. In order to avoid the air mixed with products . In this case the valve is installed in front of the pump, on top of the inlet pipe.

Working Principle
Air Release valve is a double-seat valve with a freely movable plastic ball. The ball, which is lighter than water, According the conditions of pressure to close the upper or lower valve seat.

Application
This valve used in pressure vessel or pipe system with multiple functions, negative pressure (vacuum) and adjustable pressure setting:
◆ 1）when pressure is higher than the set pressure (standard 1 bar)release air, Otherwise is closed;(pressure regulator can be set)
◆ 2）when the pipe system in vacuum (standard - 0.9 bar) valve open automatically . It ensure the equipment and related instrument security, at the same time it can meet various production process demand. This valve made as full stainless steel materials, hygienic design,
