Product Description
Stainless Steel Food Grade Pressure Relief Valves
Breather valves are safety devices required for storage tanks/containers/gas or vapor pipe lines/ reactors etc. having chemicals or any other fluid to be handled carefully.Breather valves with desiccants are used during transportation of sensitive equipments/ goods to protect from pressure differentials due to change in climatic conditions.
COMBUSTION RESEARCH ASSOCIATES manufactures Pressure Vacuum Relief Valves (PVRV), Breather Valves, Safety Relief Valves and Vacuum Breaker Valves of wide range to meet the industry requirements.In case of combustible fluids storage the safety valves should be used along with flame arrestors.

Sanitary Tank Pressure Vacuum Relief Valves work in the following ways-- From the Vacuum side, when the valve is normally closed and there is vacuum in the tank, the vacuum piston inside the valve opens automatically and draws air into the tank. In return, this keeps the pressure inside and outside the tank balanced. From the Pressure side, when the valve is normally closed and the tank pressure exceeds the rated pressure on the outside of the valve, the valve automatically opens and vents air to atmosphere.

3. How do you control the quality?
Quality control is very important to avoid material mixing and poor quality. We control the quality from beginning to the end. We only have 304 and 316L two different materials. 100% inspection on raw materials. During production, different materials in different places. After materials are finished, we choose 10% for inspection. If there is 0.1% problem in 10%, then no excuse to go ahead for inspecting 100% of the materials.
4. About chemical components
This is first concerning for customers. We take our materials to our laboratory for each lot. You may ask for the laboratory report any time.
