Pneumatic diaphragm control valve

Pneumatic diaphragm control valve takes compressed air as power source, used for automatic regulation of flow rate, pressure, temperature and liquid level of steam, water, oil and chemical medium.

It has stable output, good sealing performance and excellent explosion‑proof performance.

Widely used in chemical, petroleum, power, metallurgy, pharmaceutical and heating industries for process automatic control.

Working Principle：

Air pressure acts on the diaphragm to push the valve stem and plug to move, changing the flow area to adjust medium parameters. Matched with positioner, it realizes precise continuous regulation.
