Speciality Valve is a leading Pressure Relief Valve manufacturers in India, providing solutions that ensure system efficiency and safety. A pressure relief valve or PRV is an important device in most industries, designed to make sure pressure in a system, be it a pipeline system or even a domestic unit like a water heater, never rises above a safe limit. 

A pressure relief valve is a protection device used in preventing pressurized systems from the risk of overpressure. It relieves excess pressure in the system automatically to avoid equipment malfunction or deadly accidents. This valve is often used in industrial systems, in addition to domestic configurations such as the water heater pressure relief valve, where it protects against hazardous accumulation in hot water systems. 

Components of a pressure relief valve 

1. Spring: Gives the pressure to close the valve until the set pressure is achieved. 
2. Valve Seat: The face where the valve disc seals to avoid leakage. 
3. Valve Disc: Fluctuates to open the valve when the set pressure is achieved. 
4. Bonnet: Accommodates the spring and other inner elements. 
5. Inlet and Outlet Ports: Permit fluid to enter and leave the valve. 

Working Mechanism 

In normal working conditions, the spring maintains the valve closed. When pressure in the system goes beyond the set limit, the pressure overcomes the tension of the spring, and the valve disc is lifted along with the release of excess pressure. When the pressure returns to a safe level, the spring closes the valve by forcing the valve disc onto the seat. This same mechanism extends to house systems like a water heater pressure relief valve, which vents pressure automatically to avoid tank rupture or explosion. 

Advantages of a pressure relief valve 

• Avoid Equipment Damage: Guard against overpressure leading to equipment breakdown. 
• Improve Safety: Minimise the danger of accidents and injuries. 
• Cost-Effective: Saves on repair and replacement expenses by preventing damage. 
• Consistent Performance: Guarantees steady performance under varying conditions of pressure.
