Self-reliance type pressure pneumatic control valve of technical indicators and USES

Self-reliance type pressure pneumatic - valve does not need additional energy, can work in the absence of electric airless place, convenient and save the energy. Pressure piecewise range and cross each other, high precision of adjustment. Pressure setting can be set in a continuous during operation. After the valve pressure regulation, valve pressure before and after the valve pressure ratio of 10:1 ~ 10:8. Rubber diaphragm detection, high measurement precision, actuator. Using pressure balancing mechanism, pneumatic control valve is responsive, precise control. Direct effect on pressure pneumatic control valve is when there is no electricity, no gas occasions, use pressure control valve before (modulated medium itself K type) Or after valve ( B) Pressure constant pressure or vacuum, ancillary condenser, can be continuous use under 350 c steam, diaphragm for less than or equal to 0. 7 mpa pressure, piston used for 0. 7 ~ 2. 5 million mpa pressure. Self-reliance type pressure pneumatic - valve widely used in petroleum, chemical, electric power, metallurgy, food, textile and other industrial equipment in gas, liquid, steam medium pressure, pressure, voltage regulator.
