Product description:

ZZY-type self-acting pressure regulating valve without external energy, the use of the media itself as the power of the media to be adjusted, the introduction of the actuator control spool position, change both ends of the pressure and flow, so that before the valve (or valve) pressure stability. With sensitive, good sealing, small pressure set point fluctuations, etc., are widely used in gas, liquid and vapor pressure regulator decompression regulator or automatic control. 
 This series of products have a single seat (ZZYP), sleeve (ZZYM), two-seat (ZZYN) three structures; executive body film, piston two; role type decompression valve with the pressure regulator (B type) And pressure relief valve with pressure regulator (K type). Product nominal pressure rating PN16, 40, 64; body diameter range DN20 ~ 300; leakage levels are II, IV and VI third gear; flow characteristics for quick opening; pressure sub-adjustment from 15 ~ 2500kPa. Can be combined as needed to meet the needs of user conditions.
 

Features:

1, Self-operated pressure control valve without additional energy, can work in a non-electric gas-free place, both convenient and energy saving. 
 2, the pressure range of small and cross each other, adjust the high precision. 
 3, the pressure setting can be set continuously during operation. 
 4, after the valve pressure regulator, the pressure before the valve and valve pressure ratio of 10: 1 ~ 10: 8. 
 5, rubber diaphragm detection, the implementation of high precision detection, action sensitive. 
 6, the use of pressure balance mechanism, so that the control valve responsive and precise control.
