Pressure Relief Valves
A relief valve or pressure relief valve (PRV) is a type of safety valve used to control or limit the pressure in a system; pressure might otherwise build up and create a process upset, instrument or equipment failure, or fire. The pressure is relieved by allowing the pressurized fluid to flow from an auxiliary passage out of the system. The relief valve is designed or set to open at a predetermined set pressure to protect pressure vessels and other equipment from being subjected to pressures that exceed their design limits.
Pressure/Vacuum Relief Valve With Pressure Spring
Product Price: Rs 14,000 / PieceGet Best Price
Product Details:
| Usage/Application | Industrial |
| Pressure | 15 psig |
| Material | Stainless Steel |
| Brand | Groth |
| Valve Size | 2" |
| Model Name/Number | 1201B |
The 1200 series is designed to protect your tank from damage created by overpressure or excessive vacuum. Costly product evaporation losses due to normal tank “breathing” are greatly reduced. Because the valve retains toxic vapors, atmospheric contamination is minimized. This helps to provide increased fire protection and safety. The 1201B Pressure/Vacuum Relief Valve is a spring-loaded version of the 1200A PVRV for use at pressures of 1 PSIG and above.
Features
- Peripheral and central seat guides ensure reliable, repeatable performance

Product Details:
| Usage/Application | Industrial |
| Material | Stainless Steel |
| Brand | Groth |
| Valve Size | 2" |
| Model Name/Number | 1400 |
The Groth 1400 Series Pilot-Operated Relief Valves are used to replace weight-loaded or spring loaded valves in many applications to increase efficiency and reduce evaporation losses.
