Assistant valve enterprise to win the world
Size:NPS1/2"~16" (DN15~400)
Pressures:Class150~300 (PN16~40)
Material:Carbon Steel, Stainless Steel, Alloy Steel
End Connection:Flange
The valve, made from valve body, actuator and one pressure-preset spring, applies internal pressurizing structure, automatically adjust and stabilize the pressure by using the pressure change of medium itself. It is applicable for steam, weak corrosive gas or low-viscosity liquid, acting the downstream pressure control in the pipeline, when the downstream pressure rises up, the valve is closing to reduce the pressure.
