Self-reliance type pressure pneumatic regulator features and main technical parameters

Self-reliance type pressure pneumatic - valve does not need additional energy, it can work on occasions without electricity and gas, convenient and save 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 ~ between 10:8. Rubber diaphragm detection, high detection precision, actuator. Using pressure balancing mechanism, pneumatic control valve is responsive, precise control. Self-reliance type pressure pneumatic - valve technology parameters, nominal pressure, nominal diameter, the standard of flange, etc. Has cast steel body material ( ZG230 - 450). Casting, stainless steel ( ZG1Cr18Ni9Ti、ZG1Cr18Ni12Mo2Ti） 。 Valve core material with hard seal - stainless steel ( 1Cr18Ni9Ti、1Cr18Ni12Mo2Ti） ； Soft seal - stainless steel inlaid rubber ring. Pressure balance is stainless steel corrugated pipe ( DN15 ~ 125) , balance diaphragm ( DN150 ~ 250) 。
