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 ~ DN300, NPS t/2" ~ 12"
· Nominal pressure: PN16 - PN63, ASME CL150 ~ CL300
· Temperature range:-60° C ~+550° C
Features
· Various valve body materials for selection, such as cast steel, cast stainless steel, low-temperature and high-alloy steel or special materials
· No external energy required, with the constant pressure value before (or behind) the valve being automatically adjusted and stabilized with the pressure change of the medium only
· An ideal energy-saving product that is widely used in various industries for pressure maintaining and stabilizing of various noncorrosive media with the pressure before the valve being not greater than t.6MPa
