The pipeline gate valve is designed to meet the long-distance transportation service of crude oil and natural gas. It is designed in accordance with API 6D and has DBB function, so the valve can provide two-way switching services. Our straight-through con

Simple structure, convenient operation, convenient installation, good sealing performance, long service life, high reliability, good interchangeability of parts, and cost saving.

The stop valve is a linear motion valve, which can be used to start and stop and adjust the fluid flow. The stop valve is mainly used for throttling service and automatic control.

The stop valve opens and closes the valve with the help of a plug-shaped disc, which is tightly fixed in the valve.

Our gate valves are cheap, but durable and reliable. We believe that our deep research and development and rich production experience are important reasons why we are trustworthy.

The main difference between ball valves and globe valves is the way they close. A ball valve has a stem and a ball, which rotate horizontally and are usually called "rotary" valves. The globe valve has a stem and a plug, which stroke linearly, a

Good sealing performance improves the reliability of the system. The friction resistance is small, the opening and closing is forceful and flexible. It has a long service life and can be switched repeatedly. High pressure and high temperature resistance,

The gate valve is designed for fully open or fully closed service. They are installed in the pipeline as isolation valves and should not be used as control or regulating valves.

Concentric design wafer butterfly valve, with no back structure, rubber welded valve body, replaceable elastic seat, streamlined disc, integrated stem

The pressure-sealed gate valve is designed in accordance with API 600, suitable for high temperature and high pressure working conditions, and is widely used in nuclear power plants and thermal power plants. Compared with bolted bonnet joint valves, they

The gate valve is an energy-saving valve option because the direction of movement or gate is perpendicular to the direction of medium flow. Therefore, less power is consumed when opening or closing the gate valve compared to the shut-off valve. Because of

The valve cover provides a leak-proof closure to the body. The threaded valve stem part will pass through a hole that has a thread similar to the valve cover, and the valve stem with the threaded part extends into the same hole as the valve cover thread.

The globe valve is also a member of the linear motion valve family. Its functions include stopping and starting media and regulating the flow of media. Due to its design, the shut-off valve can provide a tight seal with less chance of leakage.

Wafer-type soft-seal butterfly valves use the flexibility of the rubber seat to easily achieve zero leakage, so they are widely used in oil fields, agriculture, water and wastewater, and mining industries. Because of its rubber-lined valve body material,

The gate valve is composed of three main parts: the valve body, the valve cover and the valve trim. The body is generally connected with other equipment through flange, thread or welding connection. The engine cover containing the moving parts is usually
