Overview

Product Details

ZZC and ZZV self operated differential (micro) pressure regulating valves are actuator products that do not require external energy. Can be used for nominal pressure PN01, PN10. Differential (micro) pressure can be adjusted in sections From 50mm W. C to 0.1MPa. It has a wide range of applications and can be used in industrial combustion systems to control the flow ratio of two materials, such as gas and air, to achieve ideal combustion. Used for sealing the oil system of hydrogen cooled generator sets, when the low-pressure end of the differential pressure valve is open to the atmosphere, it is a micro pressure valve (negative pressure of the differential pressure valve, end pressure, zero force).

Product Features

1. Adjust the set value without stopping production;

2. No packing, there is no friction when the valve stem moves up and down, and the upper seal is reliable;

3. The sensitive components of the actuator are extremely sensitive, and even tiny pressure changes can be detected;

4. The valve body is in the form of a four-way valve, and due to the K and B types, one type of valve body can be used universally.

performance parameters

Note: 1. The nominal pressure for a single seat is 0.1 MPa, and for a double seat it is 1.0 MPa.

2. The range of differential pressure regulation for two seats is 36-100KPa.
