Foshan Jinqiu Valve Co., Ltd., as a professional gate valve manufacturer and operator in China, has been committed to the research, development, production, sales, and service of various gate valves. Our high-quality wedge gate valves are opening and closing devices used in petrochemical, thermal power plant, and other fields. They are mainly used for connecting or cutting off media in oil and steam pipelines. The standards implemented cover testing, pressure, temperature, and product labeling, and are suitable for crude oil, water, and natural gas. Our company produces a complete range of products, guarantees quality, and enjoys a good reputation. In the face of fierce market competition, Jinquan always adheres to the philosophy of "quality first, integrity foremost," providing all JQF customers with timely, comprehensive, and high-quality sales services.

Wedge gate valves are one of the best-selling products of JQF Valve. They adopt a compact structural design and are available in elastic wedge single gate, rigid wedge single gate and double gate types. They have high rigidity and low flow resistance characteristics. The core feature is that they use a wedge-shaped gate as the closing element, and the fluid is opened or cut off by the vertical lifting of the gate.

Main Features

1. Compact structure, reasonable design, high rigidity, smooth flow path, and low flow coefficient.

2. Sealing surfaces are made of stainless steel and hard alloy, ensuring long service life.

3. Uses flexible graphite packing, ensuring reliable sealing and easy, flexible operation.

4. Drive methods include manual, pneumatic, electric, and gear transmission.

5. Structural forms include elastic wedge single gate valve and rigid wedge single gate valve double gate valve.

Applications

Wedge gate valves, due to the angle between their sealing surface and the vertical center line, offer superior sealing and can withstand high pressures. Generally, the valve stem undergoes tempering and surface nitriding treatment, providing excellent corrosion and abrasion resistance. The gate and seat seals are constructed using hard alloy welding, offering wear resistance, high temperature resistance, corrosion resistance, good abrasion resistance, and a long service life. A wide variety of valve body materials are available, and packing and gaskets are selected according to actual working conditions or user requirements, making them suitable for various pressures, temperatures, and media conditions. They can generally withstand pressures up to PN16 and are widely used in power, petroleum, chemical, metallurgical, mining, and wastewater treatment industries, playing a particularly significant role in power plant ash removal and coal washing plant equipment.
