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

Ball valves are more effective in forming tight seals and have higher reliability and life than gate valves, but they are more expensive. They are often used to shut down and control applications. Because the ball valve can be opened and closed instantane

You can expect the service life of the shut-off valve to be approximately 10 to 25 years, with an average of 20 years. However, if they are not "exercise" once a year or two years, then when you really need to close the valve for a pipeline emer

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

The main difference between these two types is the way they are closed. The stop valve uses a plug (stem) that closes against the flow, while the ball valve has a gate (ball) that can close the entire flow. The stop valve is suitable for adjusting the flo

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

High-performance stainless steel butterfly valves are one of the most widely used butterfly valve types in processed food-grade products. They are also used to treat corrosive fluids. Stainless steel butterfly valve adopts SS304, SS316 or SS316L body mate

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 valve seat of the gate valve is either provided integrally with the valve body or adopts a seat ring structure. The valve seat provided by the valve seat ring structure can be screwed into place or pressed into place and sealed and welded to the valve

The gate valve is a valve that completely restricts the flow of fluid and provides a full-diameter valve without changing the direction. The valve disc is appropriately called a gate here and is moved into the fluid at right angles by a threaded shaft wor

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 structure of the wafer butterfly valve is formed by the central disc rotating 90 degrees in the valve body. Using the drive type, the flow of fluid can be stopped, adjusted or started. In the wafer connection, the valve is installed between pipe flang

Resilient seat gate valves are used for purification and pumping of sewage, fire fighting systems, irrigation, industrial pipelines, etc. It has minimal head loss, 100% water tightness and full bore.

This is the connection from the actuator to the valve, which provides the driving force. The stem of the actuator control valve can be smooth, and the stem of the manual control valve can be threaded.

Control valves are an essential part of any piping unit. The basic function of these valves is to manage the flow of medium through different piping areas of a system. Ball and plug valves are two types of control valves that have similar functions and ar
