Product Description

Summary
The 30P/N/M self‑operated pressure control valve is composed of the control valve, actuator and a spring used for pressure setting.
It is suitable for controlling before‑valve pressure (when the before‑valve pressure rises, the control valve is opened) or after‑valve pressure (when the after‑valve pressure rises, the control valve is closed) in the pipes of non‑corrosive liquids, gases and steams.
It is widely used in such industries as petroleum, chemical industry, electric power, metallurgy, medicine, food, textile, machinery, heating & ventilating, etc.
