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.
