Gate valve
Product overview:
Gate valve is one of the most widely used valves in various fluid transportation projects. The elastic seat sealed gate valve adopts a novel structural design, strict manufacturing process, and high-performance new materials, overcoming the defects of poor sealing performance, easy corrosion of internal components, especially the gate plate, and rubber elastic aging of traditional gate valves. Reliable sealing performance, easy and convenient operation, simple and convenient maintenance, and long service life. Suitable for domestic water systems, water supply and drainage systems, sewage treatment systems, chemical fluid transportation systems, etc. It is used as an online cut-off device for fluid pipelines in industries such as construction, urban environmental protection, petrochemicals, pharmaceuticals, food, metallurgy, textiles, and electricity (not suitable for throttling).

Product Features:
- There are concealed rod and exposed rod structures, which can be operated by hand wheels, handles, electric, pneumatic and other devices.
- Easy installation and construction, multiple connection methods, and optional expansion function.
- The gate valve body is cast with two legs, and the valve cover is cast with two lifting rings for easy handling and storage.
- Stainless steel corrosion-resistant valve stem, trapezoidal thread rolling processing, smooth and wear-resistant threads, reducing operating torque.
- There is a guide rail system between the valve body and the gate plate. Rubber has no contact wear during lifting to prevent valve stem bending.
