ZZCP/ZZVP Self operated Differential (Micro) Pressure Regulating Valve

Product Features
HANLKA technology differential micro adjustment thin film structure self adjustment
Unique design, precise adjustment, spray coating process, exquisite appearance
Product Overview
Self operated differential (micro) pressure regulating valve is an actuator product that does not require external energy. Can be used for nominal pressures PN0.1 and PN10. Differential (micro) pressure can be adjusted in sections. From 50mm. WC to 0.1MPa. It has a wide range of applications and can be used in industrial combustion furnace systems to control the flow ratio of two materials, such as gas and air, to achieve ideal combustion. Used for the sealing oil system of hydrogen cooled generator sets, controlling the pressure difference between the sealing oil and hydrogen gas to ensure reliable sealing. When the low-pressure end of the differential pressure valve is open to the atmosphere, it is called a micro pressure valve (negative pressure, end pressure, and zero force of the differential pressure valve).
Adjust the set value without stopping production;
No packing, there is no friction when the valve stem moves up and down, and the upper seal is absolutely reliable
The sensitive components of the actuator are extremely sensitive, and even tiny pressure changes can be detected
The valve body is in a four-way form, so K and B types can be used interchangeably as one type of valve body
