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

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 gate valve has a closing/closing mechanism. There is an upward internal gate device that allows the medium to flow and closes the valve downward. A distinctive feature of the gate valve is its straight passage, which reduces pressure loss and is easy

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

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

The plug or disc is an important part of the valve. It is connected to the valve stem and can be used for throttling.

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 the product category of gate valve, we are a professional manufacturer from China, gate valve, flange gate valve supplier/factory, wholesale elastic sealing gate valve research and development and manufacturing of high-quality products, we have perfec

We produce cast iron wafer butterfly valves, with hand lever or worm gear Operator. Our Butterfly Valves are widely used in drinking water system, sewage system, fire-fighting system. Butterfly Valves can produce from size DN40 to DN2400.

Push-in joints do not require solder, glue, unions or tools. Corrosion resistant to extend service life, designed for drinking water distribution and circulating heating applications.

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 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.

Generally, gate valves are used to completely close the fluid flow in the pipeline, or to provide the full flow in the pipeline when fully opened. Therefore, it can be used in a fully closed or fully open position.

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

Types of butterfly valves: lug type butterfly valve, U-shaped flange butterfly valve, double flange butterfly valve, fluorine-lined PTFE butterfly valve, double eccentric butterfly valve and triple eccentric butterfly valve
