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 ~ 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
