PRESSURE CUM VACUUM RELIEF VALVES


 

 PRESSURE CUM VACUUM RELIEF VALVES

These are useful as relief valves for blanketed vessels in which solvents are filled & drawn out at a high flow rate. These can also be fitted, on the process vessels to safeguard the process equipment where unpredicted fluctuations in pressure may occur. By retaining toxic vapours and avoiding atmospheric contamination these help to provide increased fire protection and safety. Pressure cum vacuum relief / breather valves are designed to protect your tanks from possible casualty due to over pressure created by thermal expansion & product movement into the tank and excessive vacuum created by thermal contraction & product movement out of the tank. At the same time it minimizes costly product evaporation / loss. Continued design improvements provide these valve with high efficiency, maximum flow capacity and minimum leakage. These are available "closed end hoods" type of standard design or with "pipe-away design" for vapour recovery. These can also be offered as only the vacuum relief valves with blind flange on pressure port and vice-versa
