The working principle of the stop valve is the vertical movement of the valve disc away from the valve seat. So when the valve is closed, it will cause the space between the disc and the seat ring to close. This is why these valves are used to start, stop

The sealing ring adopts seatback type, mortise type or directly vulcanized on the valve body. The sealing surface of the valve seat flange adopts an O-ring to cooperate with the pipe flange cone, and the sealing effect is good. It is easy to disassemble a

Floating ball valves are widely used in various industries and attract more end users to replace gate valves and globe valves in cryogenic applications.

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.

The valve body and bonnet are made of castings and are connected by flange joints. The seat surface of the valve seat and the wedges conform to the API 600 standard. The seat ring is welded into the valve body.

The ball valve is designed to contain a ball in the valve. The ball valve is a form of quarter-turn valve that uses a hollow, perforated and rotating ball (called a "floating ball") to control the flow through it. It is open when the hole of the

Its working principle is to lift or press a rectangular or circular gate connected by the valve stem to the fluid path by rotating the handle wheel clockwise and counterclockwise.

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. These qualities make them an excellent choice for shut-off applications where they are generally more popular than ga

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

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.

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

The closing function of gate valves is very good. They provide laminar flow with minimal pressure loss.

The operation of the gate valve is to perform a clockwise closing (CTC) or clockwise opening (CTO) rotary movement of the valve stem. When the valve stem is operated, the gate moves up or down on the threaded part of the valve stem.

The gate valve is a two-way sealed valve. The valve body-bonnet joint and packing chamber are sealed with non-asbestos gaskets and packing to ensure a long service life.

In a system with irregular changes in high temperature, the gate valve will leak due to the load in the valve end pipe.
