    In a low-pressure gas system, there is a safety switch between the manual reset valve and zero gas governor called a _____ vaporstat In a high-pressure gas system, a low-gas-pressure switch with a ____ causes the combustion controller to secure the safety shutoff valves if the gas pressure is too low.Learn More

  • Pressure safety valve theory and PSV valve mechanism

    Aug 23, 2017 · Safety valves are designed to automatically pop open on pressure and stay open until there is a definite drop in pressure inside of the boiler. The pressure at which a PSV valve operates is known as blow down of safety valve & reseating pressure is called blow back, without chattering (opening and closing quickly).Learn More
