Bleed Valves

What are bleed valves?

Bleed valves or in other words high-pressure bleed valves are meant for releasing the trapped air using the heating system. Bleed valves are also known as Air Release Valve (ARV). The function of a bleed valve is to slowly drain off a gas or a liquid with a help of a pump, pipeline or a tank.


From pressures to temperatures, each and everything of bleed valves has specifications. The high working pressure up to 10,000 psig which is approximately 689 bar. The temperature which these valves can resist ranges from -65 to 850 degree Fahrenheit (-53 to 454-degree centigrade). Moreover, the flow coefficient in these inline bleed valve is 0.25.

The material used to design these bleed valves is 316 stainless steel, carbon steel, alloy 400, alloy C-276, alloy 625, alloy 825, alloy 2507 and brass.

Bleed valve function:

The main function of the bleed valve is to remove the liquids from the tank or a tube. Other than this, these valves are also used to remove gas from the liquid. The calipers of the hydraulic brakes are fitted in which allows the trapped air to be removed by applying a specific pressure.
