Product outline ZZYP self-reliant -like pressure regulator valve, uses is moved medium own energy is the power supply, the introduction implementing agency control valve core position, the change both sides differential pressure and the current capacity, after before causing the valve, (or valve), the pressure is stable. Has the movement to be keen, the leak-proof quality is good, the pressure setpoint fluctuates slightly and so on merits, widely applies in the gas, the liquid and the steam medium reduced pressure constant voltage or the decompression constant voltage automatic control.
This serial products has single-seat (ZZYP), sleeve (ZZYM), the double seat (ZZYN) three kind of structures; The implementing agency has film, the plunger-type two kinds; The function pattern has the reduced pressure before the valve the pressure control (B) and the decompression uses the valve the pressure control (K). The product nominal pressure rank has PN16, 40, 64; Valve chest caliber scope DN20~300; The spillage rank has II level,Level and VI level of third gear; The discharge characteristic to open quickly; Pressure partition adjustment from 15~2500kPa. May demand must combine satisfies the user operating mode request. |
