Stainless steel pilot gas regulator XTY31

Shanghai Pressure Regulating Industry Co., Ltd. Is an integrated design and manufacturing manufacturer, SHZDH product: Pilot Operated Reducing Valves, Stainless steel pressure reducing valve etc. Products, More choices, Many proven cases, Saves your sourcing effort,Strong technical capability, Ample spare parts, Fast repair, Fast response,Engineering pipe routing, Chemical fluids.

PilotGas RegulatorsControls the main valve downstream pressure by adjusting the pilot reducer output pressure, pressure can be set anywhere within the adjusting range, continuous control, achieving continuous, stepless downstream pressure regulation, supports remote, pneumatic and other control modes, downstream pressure is controlled by the reducing valve output pressure, may be equal, or varied at a set ratio, air control ratio 1: 1 to 1:100. Pilot-operated gas regulators are suitable for applications where fluid pressure requires remote or precise control.
