Summary
HDS500 series self-operated pressure regulating valve adopts external pressure taking structure. It can rely on the pressure change of the medium to achieve the purpose of automatic pressure regulating and sustaining. It has the characteristics of simple structure and reliable operation. It adopts bellows balanced type, piston balanced type, sleeve-guided type and other plum structure. The energy-saving product suitable for airless or powerless situations, which has small unbalance force and sensitive action, is widely used in various low viscosity liquids, gases and saturated steam.
This series of control valve is divided into two types which are inlet of valve pressure control and outlet of valve pressure control.
