ZZY type Self-pressure regulating valve

ZZY type Self-pressure regulating valve without external energy sources, the use of the medium itself was transferred energy as the power source, the introduction of the position of the control valve actuators, pressure and flow changes at both ends of the front valve (or valves after) the pressure is stable. A sensitive, sealing, small fluctuations in pressure set point, etc., are widely used in gas, liquid and steam pressure regulator or pressure relief regulator medium automatic control.
This series of products are single-seat (ZZYP), sleeve (ZZYM), two-seater (ZZYN) three structures; actuators film, piston two; effect types have the decompression valve pressure regulator (B type) pressure relief valve and pressure regulator before (K type). Nominal grade products are PN16,40,64; body diameter range of DN20 ~ 300; leakage levels have Class II, Ⅳ grade and Class VI third gear; flow characteristics for quick opening; pressure segment is adjustable from 15 ~ 2500kPa. May need a combination of conditions to meet user requirements.
Self-pressure regulating valve characteristics
• Self-pressure regulating valve without external energy, energy in the absence of electric airless place of work, both convenient and saves energy.
• Pressure finely segmented range and cross-cutting, high regulation accuracy.
• pressure setpoint can be set continuously during operation.
• For the pressure regulator valve, pressure over the valve and the valve before the pressure is 10: 1 to 10: 8.
• rubber diaphragm type detection, high detection precision actuators, quick action.
• Use pressure balancing mechanism, the regulator valve responsive and precise control.
