Pressure Relief Valve (Safety Relief Valve)
Premium Pressure Relief Valves & Safety Relief Valves Manufacturer
Hyperr Valves Pvt Ltd is a leading manufacturers, supplier and exporter of safety relief valve / pressure relief valve. Our Pressure Relief Valve is the ultimate safeguard for your pressurized systems, engineered to automatically release excess pressure when it exceeds a preset limit. Unlike control valves that regulate flow, this safety device stays “normally closed” and activates only when critical protection is needed to prevent catastrophic equipment failure or piping rupture.
Designed in strict accordance with ASME Section VIII and API 526, our valves feature a precision spring-loaded mechanism that ensures rapid opening (“pop” action for gas) and reliable reseating once normal pressure is restored. Modelled with SolidWorks for structural integrity, they are built to withstand the most severe industrial overpressure events.
Key Features:
- Instant Protection: Rapid response to pressure surges, providing immediate relief to protect vessels and personnel.
- Certified Compliance: Designed and tested to meet API, ASME, and ISO safety standards.
- Tight Reseating: Engineered for precise "blowdown" (re-closing difference) to minimize product loss while ensuring system stability.
- Zero Leakage: Lapped nozzle and disc seats (Stellite hard-faced) ensure API 527 seat tightness during normal operation.
- Versatile Design: Suitable for liquid, gas, and steam service (Safety Relief) with options for bellows to handle back pressure.
Applications:
- Pressure Vessels
- Boilers
- Compressor Discharge
- Storage Tanks
- Piping Systems
