Model HPRV Valve
Model HPRV (High Pressure Relief Valve) Valve
The Model HPRV is an angle body valve that holds a bubble-tight, closed position until pressure reaches an exact set point. At an exact set point, the pin buckles and the valve opens in milliseconds for immediate pressure relief. Relieves pressure to prevent pump, hose and system damage on frac fluid systems – ideal for pulsating pressure.

“POCO” Pin Design
Our drilling valve line is designed to use the “POCO” pin instead of a traditional pin. This intelligent design allows the user to change the set pressure of the valve by simply changing pins. This is done by affixing pin spacers on each end of the Rupture Pin while keeping the overall length of the pin assembly constant.
The pin is located outside the valve and is the heart of the operation, acting as the sensor and actuator. Once buckled, one person in under a minute can reset the pin in place without breaking the line.
The Model HPRV valve provides safety for a variety of pressure relief applications including but not limited to: mud, slurry, and fracing fluid relief. The valve relieves pressure to prevent pump, hose and system damage on frac fluid systems – ideal for pulsating pressure. Use instead of nitrogen assisted valves or ball & spring reset valves where you need greater accuracy and reliability. Our hydraulic fracturing and mud and slurry relief valve ranges are exceedingly popular in the Oil & Gas industry.
