The plug valve, with its simple structure and excellent sealing performance, has a wide range of applications in industrial fields. Its plug design allows for quick and safe opening and closing, making it suitable for numerous operating conditions that require strong sealing, high corrosion resistance, or frequent operation. 1. Applications Requiring High Sealing Performance The plug valve excels ...

Sleeve type plug valves, known for their excellent sealing performance and precise fluid control capabilities, are widely used in various industrial sectors. Proper installation is crucial for ensuring the valve's normal operation and extending its service life. 1. Preparation Before Installation (1) Verify Specifications and Model Before installation, check that the valve's specifications and mod...

Plug valves and gate valves are two common industrial valves that differ significantly in their structure, working principles, applications, and other aspects. 1. Structure l  Plug Valve: -Key components include the valve body, plug, and handle. -The plug is cylindrical or conical, with one or more through-holes inside. -Fluid flow is controlled by rotating the plug. l  Gate Valve: -Key ...

When installing plug valves, it is important to consider the following aspects to ensure their normal operation and prolong their service life: 1. Selecting the Appropriate Valve Type: - The installation position should facilitate operation, maintenance, and inspection. - Consider the compatibility with other pipeline equipment and the impact of surrounding environmental conditions. - Select the a...

The plug valve is a quick opening and closing valve. Plug valves are suitable for multi-channel structures, so one valve can obtain two, three or even four different flow channels. This can simplify the design of the pipeline system, reduce the amount of valves and connecting fittings. Plug valves can be divided into soft seal and hard seal structures according to different sealing materials. 1. L...

There are four common types of plug valves, each of which has specific characteristics and advantages. Lubricated plug valve The lubrication plug valve uses lubricant to reduce frictions and make each port tightly sealed. Lubricants are basicly base oils that increase the viscosity of moving parts, such as amorphous or fumed silica, which are injected between the valve plug surface and the valve b...

There are many ways to classify plug valves. In this article, we will introduce four main type of plug valves. 1. Lubricated Plug Valve A lubricated plug valve functions with the help of a lubricant (a base oil and viscosity improver) which is injected between the plug and body seat facing to reduce the frictions between them. The lubricated plug valve must be resealed after a few cycles. Due to i...
