Stainless Steel Self-

ZZY Self-pressure regulating valve without external energy, energy use was transferred media itself as the power source introduced the actuator control spool position, pressure and flow changes bend both ends of the front valve (or valve after) the pressure is stable. A sensitive, good sealing, pressure set point wave power etc, and is widely used in gas, liquid and steam medium voltage vacuum regulator or relief automatic control. This series of products are single-seat (ZZYP), sleeve (ZZYM), bis (ZZYN), three structures; IA with film, piston two; action types are back pressure valve pressure regulator (B type) and former relief valve pressure regulator (K type). Nominal grade products have PN16,40,64; body diameter range of DN20 ~ 300; leakage levels have Class II, IV and VI grade level third gear; quick opening flow characteristics; pressure segment is adjustable from 15 ~ 2500Kpa. Users may need to meet the conditions required combination. Features Self-pressure regulating valve without external energy, energy without electricity airless place of work, convenient and saves energy. Fine pressure segment range and cross-cutting, high regulation accuracy. Pressure setpoint can be set continuously during operation. After pressure regulator valve, the valve before the pressure ratio of the pressure and the valve may be 10: 1 to 10: 8. Rubber diaphragm-type detector, high measurement precision actuators, quick action. Using pressure balance mechanism, the regulator valve responsive and precise control.
