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

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

There are many types of gate valves, such as full bore gate valves, parallel disc gate valves, solid wedge gate valves, flexible wedge gate valves, split wedge gate valves, vertical stem gate valves, and non-vertical stem gate valves.

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,

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.

Cast iron gate valves are used in commercial and industrial applications. Its typical services include: hot and cold water, HVAC, steam, gas and other general utility services.

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.

Globe valves are considered the industry standard for control valves because they are good at regulating flow, while ball valves are more suitable for on/off control without pressure drop.

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

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

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

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.

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.

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

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.
