Electrical Gate Valve

JQF Valve factory not only manufactures various standard valves, but also designs and produces valves according to customer requirements. Our high-quality Electrical Gate Valve is an automated valve device that integrates an electric actuator with a gate valve body connected by a welded end. It realizes remote control, rapid opening and closing, and automated management of valves. It is particularly suitable for high-pressure, high-temperature, high-risk, or hard-to-access working conditions and is a key piece of equipment for modern industrial pipeline automation control.

Electrical gate valves are suitable for applications that require complete opening or complete closing. In short, they are used as on/off switches, typically installed in pipelines as isolation valves, and are not suitable for flow control. When the valve is fully open, the passage is completely unobstructed, allowing the medium to flow straight through with virtually no pressure loss. Therefore, they are ideal for systems that prioritize low pressure loss and require an unobstructed flow path.

Features

1. Compact structure, reasonable design, good valve rigidity, smooth flow path, and low flow coefficient.
2. Sealing surfaces are made of stainless steel and hard alloy materials, ensuring a long service life.
3. The Electrical Gate Valve uses flexible graphite packing, ensuring reliable sealing and easy, flexible operation.
4. The Electrical Gate Valve can be driven manually, pneumatically, electrically, or by gear.
5. Three structural options are available: flexible wedge single gate, rigid wedge single gate, and double gate.
