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

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.

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

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

In the shut-off valve, the flow of water is controlled by a movable mandrel, and the flow of water is restricted by lowering the mandrel to a fixed valve seat.

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 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

Types of butterfly valves: lug type butterfly valve, U-shaped flange butterfly valve, double flange butterfly valve, fluorine-lined PTFE butterfly valve, double eccentric butterfly valve and triple eccentric butterfly valve

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.

The manual gate valve is operated by a simple handwheel to raise the valve stem and gate. When closed, the gate rests on a seat ring, both of which are specially treated to provide a reliable closure.

Ball valves and plug valves are very similar in basic functions and applications. Both are control valves used to provide tight shutoff in different types of piping units. They also work on the same basic principle, that is, using a porous disk to start o

The gate valve is a two-way sealed valve. The valve body-bonnet joint and packing chamber are sealed with non-asbestos gaskets and packing to ensure a long service life.

The pipeline gate valve is designed to meet the long-distance transportation service of crude oil and natural gas. It is designed in accordance with API 6D and has DBB function, so the valve can provide two-way switching services. Our straight-through con

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.

Ball valves are valued for their long service life and excellent performance even after many years of use. Inside the ball valve, the ball is usually drilled from one end to the other, and is usually made of brass, chrome brass, or stainless steel. A leve
