The gate valve is externally threaded and yoke type full bore, with elastic wedge and rising stem.

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

Good sealing performance improves the reliability of the system. The friction resistance is small, the opening and closing is forceful and flexible. It has a long service life and can be switched repeatedly. High pressure and high temperature resistance,

Butterfly valves can be used in the shipbuilding industry, water supply and drainage, fire fighting, shipbuilding, water treatment and other systems.

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 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.

Ball valves are widely used in petroleum and natural gas, chemical and petrochemical, food industry, water supply, water treatment, building construction, light industry, power generation, pharmaceuticals, biotechnology, laboratory equipment, marine and o

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

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.

If the flow, volume and pressure can be adjusted frequently, the stop valve can be used as a control valve. The design of the shut-off valve makes it very suitable for flow regulation and start and stop flow.

You can expect the service life of the shut-off valve to be approximately 10 to 25 years, with an average of 20 years. However, if they are not "exercise" once a year or two years, then when you really need to close the valve for a pipeline emer

Control valves are an essential part of any piping unit. The basic function of these valves is to manage the flow of medium through different piping areas of a system. Ball and plug valves are two types of control valves that have similar functions and ar

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

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.
