The most common causes of gate valve failure are wear and corrosion. Over time, gate valves tend to wear out. Corrosion can cause the disc to get stuck in the open or closed position. When the handle is stressed, the valve stem leading from the handle to

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

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.

Ball valves are widely used in petroleum and natural gas, chemical and petrochemical, food industry, water supply, water treatment, building construction, light industry, power generation, pharmaceuticals, biotechnology, laboratory equipment, marine and o

For non-vertical stem type valves, if the valve is opened, the stem will not move upward. The stem is screwed into the dish. When the handwheel on the valve stem rotates, the disc moves up or down along the valve stem on the thread, while the valve stem r

The three-way ball valve is made of stainless steel and can withstand a working pressure of 1000 PSI. The available ports are L-Port or T-Port. The ball valve is connected at the threaded end: BSPP or NPT.

These shut-off valves must not be used for on/off service because it is impossible to achieve a tight seal. The disc in the valve can be completely removed from the flow path, or the flow path can be completely closed.

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,

Electric actuator ball valves have full-diameter models, some are cavity-filled, and some are V-shaped ball valves. Designed for throttling or switching applications in a variety of industries, including pulp and paper, chemical, power, oil and gas, and m

Wafer type is a common style of butterfly valve, which is cheaper than lug type. The wafer butterfly valve is installed between two flanges. The valve is held in place from flange to flange by using bolts or studs and nuts. Of course, this type of install

Because of its ability to cut off liquids, gate valves are often used in the petroleum industry. For extremely viscous fluids, special valves commonly called knife valves are used to cut off the liquid. A typical gate valve is designed to be fully open or

We are the world\'s most popular supplier of gate valves in China because we provide high-quality service and high-quality gate valves. Due to the top quality of our gate valve, it is suitable for a wide range of industrial and commercial applications. We

Gate valves Gate valves are called rising valves or non-rising valves. Around the non-vertical stem gate valve, the stem is screwed into the gate around the lower end surface. Because the handwheel around the valve stem rotates, the gate will move the val

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.

Gate valves are widely used in all types of applications, suitable for above-ground and underground installations. Especially for underground installations, it is important to choose the correct type of valve to avoid high replacement costs.
