Type ZZY since type pressure pneumatic - valve structure and characteristics

ZZY self-reliance type pneumatic pressure regulator ( Self-reliance type pressure control valve) Without additional energy, use energy modulated medium itself as the source of power, introducing device, control valve core position change at the ends of the bending differential pressure and flow, make the valve before ( Or after valve) Pressure stability. Action sensitive, good sealing, the advantages of small pressure set point wave power, self-reliance type pressure control valve is widely used in gas, liquid and steam medium pressure regulated or pressure regulator, automatic control. Since the pressure control valve have single-seat ( ZZYP) And the sleeve ( ZZYM) , two-seat ( ZZYN) Three kinds of structure; A diaphragm, two piston actuator; Function type have after decompression with valve pressure regulation ( B) And pressure relief valve pressure regulation (before K type) 。 The nominal pressure level products are PN1. 6, 4. 0, 6. 4. Body diameter range DN15 ~ 250; Leakage level class II, IV and VI three gears; Flow characteristic of quick opening; Pressure block adjustment from 15 to 2500 kpa. Can be combined according to the need to satisfy the working condition of the user requirements. 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.
