These shut-off valves have one or more ports, and their valve bodies are spherical around the port area.

Gate valves are very reliable in shutting off the water supply. They are usually used as shut-off valves for the main water supply line and branch water supply lines, although ball valves are gradually becoming more and more popular in these applications.

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.

Floating ball valves are widely used in various industries and attract more end users to replace gate valves and globe valves in cryogenic applications.

The gate valve cannot be opened and closed quickly. To fully open or close the wheel or gearbox actuator, the shaft should be rotated to the number of fully open revolutions. The number of full-open revolutions is equal to the pitch.

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.

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

A three-way ball valve is a three-way valve that allows fluid to flow to an alternative path to the hydraulic system. It allows fluid to enter and exit the valve through more than one port.

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

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

Forged steel gate valves are available in three bonnet designs. The first design is a bolted bonnet with male and female joints and spiral wound gaskets, made of F304/graphite. Ring joint gaskets are also available on request. The second design is a welde

When the handle wheel is turned clockwise, steam and steam move down through the fluid flow, and the gate is squeezed between the two valve seats, so that no fluid leakage occurs when the valve is completely closed.

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.

Because of its ability to cut off liquids, gate valves are often used in the petroleum industry. For extremely viscous fluids, special valves commonly called knife valves are used to cut off the liquid. A typical gate valve is designed to be fully open or

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.
