Self-operated Pressure Regulator

Self-operated Pressure Regulator is composed of the control valve, actuator and a spring used for pressure setting.
It is suitable for controlling input/upstream pressure of valve(when the upstream pressure rises then the control valve is opened) or output/downstream pressure(when the downstream pressure rises then the control valve is closed) in the pipes of non-corrosive liquids, gases and steams.
It is widely used in such industries as petroleum, chemical industry, power plant, metallurgy, medicine, food industry, textile, machinery, heating and ventilating, etc.
