نام انگلیسی:
Diaphragm valve ZZYP-16II
برند:
Hollysys
مشخصات:
Control valves applied to occasions where there is no external energy on site, the control accuracy is not high, and automatic pressure stabilization control is required.
Features
Various valve body materials for selection, such as cast steel, cast stainless steel, low-temperature and high-alloy steel or special materials
Improved control accuracy, being about twice as accurate as that of ZZY self-operated type
Large pressure reducing ratio, for example the differential pressure ratio reaches 1600 (0.8MPa before the valve and 50mmH20 behind the valve)
Pressure setting on the controller supported, which is convenient, quick and labor-saving, and allows continuous setting in running state
Highly sensitive, being capable of sensing very small pressure changes
Often adopted for the nitrogen sealing system of storage tanks to adjust the pressure of nitrogen in the tank
