ZZYP-16B self operated pressure regulating valve

ZZYP-16B self operated pressure regulating valve

Product introduction: ZZY type self operated pressure regulating valve does not need additional energy. It uses the self energy of the regulated medium and the power source to introduce the actuator to control the position of the valve core, and changes the pressure difference and flow at both ends to stabilize the pressure in front of (or behind) the valve. It has the advantages of sensitive action, good sealing, low power of pressure set point wave and so on. It is widely used in the automatic control of pressure reduction and pressure stabilization of gas, liquid and steam medium.

Products Details

ZZYP-16B self operated pressure regulating valve

Product features:

1. The self operated pressure regulating valve does not need additional energy, and can work in places without electricity and gas, which is convenient and energy-saving.
2. The pressure section range is fine and cross each other, and the adjustment precision is high.
3. The pressure setting can be set continuously during operation.
4. To adjust the pressure behind the valve, the ratio of the pressure in front of the valve and the pressure behind the valve can be 10:1-10:8.
5. Rubber diaphragm type detection, high precision and sensitive action of actuator.

6. The pressure balance mechanism makes the control valve sensitive and accurate.
