Pressure Relief Valves
Pressure/Vacuum Relief Valve With Pressure Spring
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
- A wide seat and air-cushion seal keeps leakage low long after the valve is put in service
- Self-draining housing body and drip rings protect seating surfaces from condensate and freezing, increasing operational reliability
- Fluoropolymer seating diaphragms are standard to minimize sticking caused by resinous vapors and atmospheric moisture

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. Several advantages are obtained over the traditional valves. For example, the process pressures may be closer to the set pressure than would be considered prudent and safe with the traditional valve. Additionally, greater conservation is obtained due to minimum product loss which in turn provides increased profits.
Features
• Ease of precision settings
• Only the pilot needs to be set
• Lower profile and weight than spring operated models for high settings
• Remote pilot sensing option allows the pilot to sense the true system pressure
• Remote or manual blowdown available
• Main valve remains tight to set pressure
• Full open at 10% overpressure
• Modulating action conserves product
• Soft seating creates tight seal to conserve product and minimize valve wear
• Top entry allows valve to be services without removal from mounting
