ZZC (V) self-operated differential (micro) pressure regulating valve

Self-operated differential (micro) pressure regulating valve is an actuator product that does not require external energy. Available for nominal pressure. Differential (micro) pressure can be adjusted in sections. From... to... It is widely used in industrial furnace systems. Control the flow ratio of two materials such as gas and air to achieve ideal combustion. It is used in the sealing oil system of hydrogen-cooled power generation units to control the pressure difference between the sealing oil and hydrogen to ensure reliable sealing. When the low-pressure end of the differential pressure valve is open to the atmosphere, it is a micro-pressure valve (the pressure at the negative pressure end of the differential pressure valve is zero). There are two types of differential (micro) pressure regulating valves: type and type. The initial position of the valve core is normally open and closed when the differential (micro) pressure increases. The initial position of the valve core is normally closed and opens when the differential (micro) pressure increases.
Features
The set value can be adjusted without stopping production
There is no friction when the valve stem moves up and down without packing. The upper seal is absolutely reliable
The actuator's sensitive components are extremely sensitive. The pressure change will be sensed
The valve body is a four-way type, so the same type of valve body can be used.
Application
． Hydrogen-cooled generator set sealing oil system
． Circulation air volume control of fan heating system
． Ratio control of two gas flow rates
D. Pump bypass adjustment
