In the 19th century, due to the increasing use of gate valves in industrial operations, their intensive development moved forward rapidly. Over time, the materials involved in manufacturing have been improved and modified to suit different applications.

The assembly, start-up, and maintenance of gate valves require a lot of space.

Compared with ball valves, gate valves require multiple turns to fully open. The valve is not suitable for throttling or control, because partial opening will cause damage to the gate and wear of the valve seat. In addition, some valve closures can cause

They are used as isolation valves in pipelines and should not be used as control or regulating valves. The operation of the gate valve is accomplished by turning the valve stem clockwise to close (CTC) or clockwise to open (CTO). When you turn the stem, t

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 gate valve cannot be opened and closed quickly. To fully open or close the wheel or gearbox actuator, the shaft should be rotated to the number of fully open revolutions. The number of full-open revolutions is equal to the pitch.

A stainless steel 3/4 ball valve is considered not only rugged and durable, but they also perform well after many cycles. In addition, the reliability of stainless steel mini ball valves is also worthy of attention, because they can be safely closed even

When the handle wheel is turned clockwise, steam and steam move down through the fluid flow, and the gate is squeezed between the two valve seats, so that no fluid leakage occurs when the valve is completely closed.

We test every valve during the production process, and carry out quality control in all processes such as forging, processing, and assembly to ensure quality.

Ball valve is a form of right-angle rotary valve, which uses a hollow, perforated and rotating ball to control it. It is open when the hole of the ball is aligned with the hole of the ball, and it is closed when it is rotated 90 degrees by the valve handl

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.

The valve body is made of 304 stainless steel, which is rust-proof and has a long service life. The ball valve is durable, performs well after many cycles, and is reliable, and can be safely closed even after long periods of non-use.

The valve cage is a part of the valve, which surrounds the valve plug and is located in the valve body. The valve cage is the main component that determines the fluid flow in the valve. As the stopper moves, more cage openings are exposed and the flow rat

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

Gate valves serve to cut the medium flow in the piping system, widely used in the field of potable water, water supply and drainage, sewage disposal, irrigation, air conditioning, fire protection as well as chemical and energy industry.
