Product Description

Application
·  Complying with GB, ANSI and other standards
·  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
·  Nominal diameter: DN15 ~ DN150, NPS 1/2" ~ 6"
·  Nominal pressure: PN16, ASME CL150
·  Medium temperature: -40° C ~ +80° C

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
