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.

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.

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

Globe valves are considered the industry standard for control valves because they are good at regulating flow, while ball valves are more suitable for on/off control without pressure drop.

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.

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,

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.

The plug or disc is an important part of the valve. It is connected to the valve stem and can be used for throttling.

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.

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

The valve body and bonnet are made of castings and are connected by flange joints. The seat surface of the valve seat and the wedges conform to the API 600 standard. The seat ring is welded into the valve body.

A stainless steel 3/4 ball valve is considered not only rugged and durable, but they also perform well after many cycles. In addition, the reliability of stainless steel mini ball valves is also worthy of attention, because they can be safely closed even

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

Gate valves are used in a variety of industrial applications, including oil and gas, pharmaceuticals, manufacturing, automobiles, and ships.

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.
