ZZC/ZZV self operated differential (micro) pressure valve
Instructions for Use 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 called a micro pressure valve (negative pressure, end pressure, and zero force of the differential pressure valve)
Product Features 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 good and 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, and both K and B types can be used interchangeably
Ordering Instructions Name and model of regulating valve Nominal pressure Mpa Nominal diameter (mm) Rated flow coefficient (Kv) Inherent flow characteristics medium name Working temperature and range Operation mode of the whole machine Pressure set point and adjustment range Valve body, valve internals, and packing materials Attached attachments Other special requirements |
