CONVENTIONAL SAFETY RELIEF VALVE MANUFACTURERS IN INDIA 

Speciality Valve has distinguished itself as one of the best Safety Relief Valve Manufacturers in India, providing reliable high-performance valves with a view to safeguarding equipment and systems against overpressure. Our safety valves are crafted meticulously and adhere to the highest safety standards for industries. 

Meaning: Safety Relief Valve 

A safety relief valve is a mechanical device to automatically open and allow too much pressure from a system to be released and therefore avoid any damage or failure. It is a combination of both the safety valves (utilized for gases) and relief valves (utilized for liquids) and provides adaptable protection in mixed-phase systems. 

Difference Between Conventional Safety Valve & Safety Relief Valve? 

• Conventional Safety Valve: Utilized mostly in gas or vapor systems. 

• Safety Relief Valve: Either gas or liquid service is applicable. 

• Conventional Safety Valve: Backpressure sensitive. 

• Safety Relief Valve: Capable of withstanding moderate backpressure. 

• Conventional: Fully opens at set pressure. 

• Safety Relief: Regulates open proportionally with system pressure. 

• Conventional: Typical pressurized systems. 

• Safety Relief: Dynamic systems with changing pressure relationships. 

Why Required? 

Safety relief valves are crucial to avoid disastrous failure caused by overpressure in storage tanks, pipelines, and process equipment. They promote safety in operation and regulatory compliance within industry. 

Key Components of Safety Relief Valve 

• Valve body 

• Inlet and outlet ports 

• Spring mechanism 

• Disc and seat 

• Bonnet 

• Adjusting screw 

Working Mechanism  

When the system pressure is above a predetermined set point, the spring-loaded disc rises, permitting the surplus pressure to flow out. When pressure falls to a normal safe level, the spring resets the disc, closing the valve and ensuring regular operations. 

Benefits of Safety Relief Valve 

• Protection against equipment damage and downtime 

• Improves operational safety 

• Consistent performance at high pressure 

• Automatic reset upon operation 

• Low maintenance 

• Meets ASME and ISO standards 

Functions 

• Pressure relief
