Top-guided structure with multi-spring diaphragm actuator, designed for reliable shutoff and process control applications.
Request a QuoteWUYI's pneumatic diaphragm shut-off valve adopts a top-guided structure and is equipped with a multi-spring diaphragm actuator. Valve body options include single-seat, cage, and three-way types. It features a compact design, lightweight structure, sensitive response, S-shaped flow path for low pressure loss, high flow capacity, and easy maintenance. The valve receives control signals to shut off, open, or redirect the flow of media, enabling automatic control of process parameters such as pressure, flow, temperature, or liquid level. It is widely used in environmental protection, water treatment, petroleum, chemical, metallurgy, power, light industry, and textile industries for automatic and remote control systems.
