Sanitary Tank Pressure Vacuum Relief Valve(DY-V155)
Application
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.
DEYI 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.

Stainless Steel Sanitary Pressure Vacuum 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.
