Description Material Performance Product Size Specifications

ZZV, ZZC series of self differential pressure control valve can be used for the nominal pressure PN0.1, PN10. Differential (micro) pressure can be segmented regulation. From 50mm.WC to 0.1MPa. Self operated differential pressure control valve is widely used, can be used for industrial combustion furnace system, control two kinds of materials, such as gas, air flow ratio, in order to achieve the ideal combustion. Used for sealing oil system of hydrogen cooled generator set to control the pressure difference between the seal oil and hydrogen gas to ensure reliable sealing. When the pressure valve of the low-pressure end through the atmosphere is the micro pressure (differential pressure valve valve pressure, end pressure, force is zero).
Note: parameters are for reference only, or are not full. Valve can be used in accordance with the requirements of different pressure, material, diameter, drive, etc.. Specific please contact or online advisory contact.
