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.

Resilient seat gate valves are used for purification and pumping of sewage, fire fighting systems, irrigation, industrial pipelines, etc. It has minimal head loss, 100% water tightness and full bore.

For the product category of gate valve, we are a professional manufacturer from China, gate valve, flange gate valve supplier/factory, wholesale elastic sealing gate valve research and development and manufacturing of high-quality products, we have perfec

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

Do not use the valve as a crowbar to open the flange, as this may cause damage to the flange area and/or damage to the O-ring seal.

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

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

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

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

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

The working principle of the stop valve is the vertical movement of the valve disc away from the valve seat. So when the valve is closed, it will cause the space between the disc and the seat ring to close. This is why these valves are used to start, stop

Wafer-type soft-seal butterfly valves use the flexibility of the rubber seat to easily achieve zero leakage, so they are widely used in oil fields, agriculture, water and wastewater, and mining industries. Because of its rubber-lined valve body material,

The gate valve has a closing/closing mechanism. There is an upward internal gate device that allows the medium to flow and closes the valve downward. A distinctive feature of the gate valve is its straight passage, which reduces pressure loss and is easy

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

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.
