The clean service pressure relief valve from Rupture Pin Technology (RPT) uses a precise pin as the sensor and actuator.
The valve is downstream balanced so it senses only upstream pressure, thus downstream containment vessel pressure will not change the set pressure. Accurate, low set pressures are possible.
RPT has over 25 years experience building relief valves and takes pride in making custom valves to take on “Mission Impossible” projects.
The new Clampseal® line from Conval, available in single and double bellows, allow for zero emissions and are ideal for applications where packed valves may not reliably contain light gases or hazardous system fluids due to leakage in the stem/packing seal area or stuffing box wall/packing seal area.
