They are used as isolation valves in pipelines and should not be used as control or regulating valves. The operation of the gate valve is accomplished by turning the valve stem clockwise to close (CTC) or clockwise to open (CTO). When you turn the stem, t

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

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

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 three-way ball valve is made of stainless steel and can withstand a working pressure of 1000 PSI. The available ports are L-Port or T-Port. The ball valve is connected at the threaded end: BSPP or NPT.

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 three-piece ball valve uses the same dynamic multi-ring gland system as the needle valve to provide higher strength and integrity. When combined with the blowout prevention rear seat valve stem, it can ensure that it can withstand all operating proces

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 valve is bidirectional and can be installed in any direction relative to the water flow. The valve will control the flow equally in either direction. In order to obtain the best valve control and stable performance, the inlet straight pipe section sho

The gate valve is designed for fully open or fully closed service. They are installed in the pipeline as isolation valves and should not be used as control or regulating valves.

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 valve is made of stainless steel and the material is 304/316. They can be used to control the flow of water, oil and gas, including various corrosive and radioactive media.

Our gate valve is more effective and saves installation space. It is widely used in urban water supply, sewage treatment, construction industry, petroleum pipeline, chemical industry, food, pharmaceutical, textile, electric power, shipbuilding, metallurgy

Our company can also provide customized valve services according to your requirements. Feel free to contact us for more information or to request a complete product category.

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.
