Pneumatic gate valve
The Pneumatic Gate Valve combines a high-performance gate valve with a pneumatic actuator to achieve automatic remote operation. Designed for rapid opening and closing, excellent sealing performance, and minimal pressure loss, it is widely used in water treatment, chemical processing, oil & gas, power generation, and industrial automation systems.
Pneumatic Gate Valve
The Pneumatic Gate Valve is an automated isolation valve that utilizes compressed air to operate the valve stem and gate mechanism. It is specifically designed for applications requiring reliable shut-off, remote control, and integration into automated process systems.
With a full-bore design, the valve provides minimal flow resistance and allows unrestricted media flow when fully open. Pneumatic actuation ensures fast response times, improved operational safety, and reduced manual labor requirements.
As a professional industrial valve manufacturer, we provide comprehensive OEM and ODM solutions for global customers.
