It is the default for the adjustment of the spring or lever space pressure, based on the foam cement on the use of the television and affirmation of the relief valve emissions, as a safety valve throat diameter of valve. When the system pressure of the valve opening and closing slide set shuttle Industrial Valves inlet pressure after a pilot valve to discharge, because of the high pressure system, help the main valve pressure chamber pressure at the back of a chair, moving through frequent closed input channel, interrupt the flow of fluid valve, the main Industrial Valves, when the pressure is steep the main valve of the valve is full paper put, main drainage valve stents. 。 Performance and safety valve opening, high back pressure. Pilot valve to detract from the harmful gas emissions and pollution is not in favor of the flow in the middle. Adjustable opening pressure. Safety valve closed around soft seat cushion to ensure satisfactory tightly closed. When the system pressure is lower than a certain value, the valve spring force to overcome the shuttle valve inlet pressure to give mobile force do, try to slide seat and office positions except open travel frequently, and finally return to the main dome of the liquid valve chamber, close the valve. In nearby set pressure relief valve to allow the office stress. For fixed office pressure relief Industrial Valves, pilot operated relief valve temperature is dependent on temperature, calculate the relief valve set pressure. Pilot operated relief valve is especially suitable for high pressure, large flow, high pressure and facility location is compact structure, space applications. Will be less pressure, in all things and rapidly-changing execution relief valve main valve. Q: pilot operated relief valve structure, work principle of Marine valves and use a: pilot operated relief valve is a kind of has a special structure of the relief valve, it is suitable for use in the place of high temperature and high pressure, is a good deputy fuel natural gas chemical industry, etc. Security pilot valve spring changes is the main advantage of the direct indirect influence to stem valves, in order to increase the sharpness and plug on the life of the main valve housing, double shell, with high precision, good reproducibility, backseat rapidly-changing operation, there is no escape, discharge, high back pressure office office for a long period of time they are mainly used for fuel and natural gas, chemical, electric, metal, and the urban atmospheric pressure indentation machine, vessels, overpressure try our best to take care of facilities. New structure, consists of a main valve and pilot valve valve answer television in own main valve moves the system pressure feedback. Can online testing of the relief valve set pressure. A pilot operated relief valve is mainly used for fuel and natural gas, chemical, electronics, metal, and in the city of compressed natural gas equipment, pressure vessel, pressure pipe try our best to take care of equipment. If the system running normally, pilot valve closed condition, through the intake manifold pressure stem valve and main valve, piping system pressure groups on the dome of the shutter, when the main valve system to initiation of electricity, directly to the main valve closed down. Its main strengths is the change in the spring, the direct indirect influence on the avail of valve stem, to increase its acuity degree level and the main valve piston sleeve double operation, high precision, good repeatability, quickly at the back of a chair tightly closed, high back pressure, no leakage, use fixed number of year of the survival of long, safe reliable, it can also correct the network repeatedly rev emissions even could skip the back row chair, closed moderate to protect. Notes to the order: The national standard) A, A: B: product name, model, nominal size medium and temperature, pressure range C: whether there is attachment, delivery time, and special requirements so that we can correct selection for you. Second, if the valve has been selected by design unit of our company model, please order according to the valves parameters directly with our sales center.
