ZZYP-16II Controller Operation Type Self-operated Pressure Control Valve
Product Description
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
-
Pressure setting on the controller supported, which is convenient, quick and labor-saving, and allows continuous setting in running state
-
Improved control accuracy, being about twice as accurate as that of ZZY self-operated type
-
Highly sensitive, being capable of sensing very small pressure changes
-
Large pressure reducing ratio, for example the differential pressure ratio reaches 1600 (0.8MPa before the valve and 50mmH20 behind the valve)
-
Often adopted for the nitrogen sealing system of storage tanks to adjust the pressure of nitrogen in the tank
