|Product introduction: ZZY self operated pressure regulating valve does not need additional energy, and uses the energy of the adjusted medium as the power source to introduce the actuator to control the position of the spool, change the pressure difference and flow at the two ends, and stabilize the pressure before or after the valve. It has many advantages, such as sensitive action, good sealing, small pressure setting point wave power and so on. It is widely used in gas, liquid and steam medium pressure reduction, pressure regulation or automatic control of pressure relief and voltage stabilization.|
This series of products have single seat (ZZYP), sleeve (ZZYM), double (ZZYN), three kinds of structure; actuator has film type, piston type two; action type has reduced pressure valve after pressure adjustment (B type) and relief valve before valve pressure regulation (K type). Nominal grade products are PN16, 40, 64; body diameter range of DN20 ~ 300; leakage levels are II grade, IV grade and VI grade three; quick opening flow characteristics; pressure regulation from 15 to 2500Kpa. Can be assembled according to the requirements to meet the user's working conditions.
The self operated pressure regulating valve does not need additional energy, and can work in the place without electricity and gas, which is convenient and saves energy.
The pressure section range is fine and cross each other, and the adjustment precision is high.
The pressure setting value can be set continuously during operation.
Adjustment of the valve after the pressure valve before the pressure valve after the pressure ratio and 10:1 ~ 10:8.
Rubber diaphragm type detection, the implementation of high precision measurement, sensitive action.
The pressure regulating mechanism is adopted to make the regulating valve sensitive and accurate.
