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

The stop valve is a linear motion valve, which can be used to start and stop and adjust the fluid flow. The stop valve is mainly used for throttling service and automatic control.

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 gate valve is not suitable for throttling volume. Due to the design of the valve, a partially opened gate of the fluid flow will cause serious damage to the valve, so flow control is difficult. Unless specifically authorized by the manufacturer, the g

The sealing ring adopts seatback type, mortise type or directly vulcanized on the valve body. The sealing surface of the valve seat flange adopts an O-ring to cooperate with the pipe flange cone, and the sealing effect is good. It is easy to disassemble a

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 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.

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 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.

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

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 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.

Gate valves are widely used in pipelines to transport media. Gate valves can be divided into wedge gate valves, flat gate valves, parallel double gate valves according to the form of valve seats. The product can have a longer service life. It can be insta

Wafer type is a common style of butterfly valve, which is cheaper than lug type. The wafer butterfly valve is installed between two flanges. The valve is held in place from flange to flange by using bolts or studs and nuts. Of course, this type of install

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.
