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.

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 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.

Gate valves are used in a variety of industrial applications, including oil and gas, pharmaceuticals, manufacturing, automobiles, and ships.

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.

The gate valve can provide different discs or wedges. The range of the gate valve is usually determined by the type of wedge used.

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 main difference between ball valves and globe valves is the way they close. A ball valve has a stem and a ball, which rotate horizontally and are usually called "rotary" valves. The globe valve has a stem and a plug, which stroke linearly, a

Ball valves are often used for steam, water, oil, gas, air, and corrosive fluids. They can handle slurries and dusty dry fluids. The ball valve is not used for abrasive and fibrous materials, because it will damage the surface of the valve seat and valve

For decades, globe valves have been considered the industry standard for control valves. They are designed with a stem that moves up and down inside the valve to control flow. They are usually used in hot and cold water coils, and larger models are usuall

The pressure-sealed gate valve is designed in accordance with API 600, suitable for high temperature and high pressure working conditions, and is widely used in nuclear power plants and thermal power plants. Compared with bolted bonnet joint valves, they

Because of their spherical shape, these valves are called shut-off valves, and an internal baffle separates the two halves of the valve body. The moving part of the shut-off valve is composed of the valve disc, the valve stem and the hand wheel.

The gate valve is the most common valve in the water supply system. It represents a linear motion isolation valve with the function of stopping or allowing flow. The gate valve is named after the closing element slides into the flow stream to provide clos

Concentric design wafer butterfly valve, with no back structure, rubber welded valve body, replaceable elastic seat, streamlined disc, integrated stem

This kind of gate valve is more flexible, because its gate can move up or down, there is no obstacle to the flow of fluid or gas, thus ensuring less friction.
