Plug valve
There are various forms of channels for plug valves, and the common straight through type is mainly used to cut off fluids. Three way and four-way plug valves are suitable for switching between multiple pipelines such as fluid direction change. Plug valves mainly use plug bodies with through holes as opening and closing components. The plug body rotates 90 degrees with the valve stem to achieve opening and closing actions. A small unfilled plug valve is also known as a "cock". The plug valve produced by Shanghai Meiyanyi Pump Valve has a simple structure, quick opening and closing, and low fluid resistance, making it one of the earliest developed valves. In order to expand the application scope of plug valves, we have developed a new structure of oil lubricated plug valves. Specially made lubricating grease is injected from the top of the plug body into the space between the valve body taper hole and the plug body, forming an oil film to reduce the opening and closing torque, improve sealing performance and service life. Its working pressure can reach 64 megapascals, the highest working temperature can reach 325 ℃, and the maximum diameter can reach 600 millimeters. Plug valves mainly include straight through plug valves, three-way plug valves, four-way plug valves, inverted oil sealed plug valves, and are also divided into T-type and L-type models and specifications. Large plug valves are also known as conventional valves and are used in pipeline equipment such as aviation kerosene, light oil, natural gas, liquefied gas, pipeline gas, chemical media, etc. The following product pictures are for reference only.

Straight through plug valve
A straight through plug valve refers to the channel structure of a plug valve, where the inlet and outlet are on the same horizontal line. The closing element or plunger shaped rotary valve of a straight through plug valve rotates 90 degrees to connect or separate the channel port on the valve plug and the channel port on the valve body, achieving opening or closing. The shape of its valve plug can be cylindrical or conical, and the channels can be rectangular or trapezoidal, respectively. This design makes the structure of the plug valve lightweight and suitable for cutting off and connecting media as well as diverting flow. The straight through plug valves produced by Shanghai Meiyanyi Pump Valve have two types: flange connection and internal thread connection, which are widely used in various important industrial fields such as petroleum, chemical, chemical, and new energy materials. The quality is stable, and new and old users are welcome to contact us for purchase.View details>>

Three way plug valve
A three-way plug valve refers to a plug valve with a channel structure in three different directions, divided into T-shaped and L-shaped tees. It is mainly used in control systems in industrial processes, as well as for merging or diverting media in pipeline equipment, and for reversing direction. The three-way plug valve mainly uses a plug body with a T-shaped or L-shaped through-hole as the opening and closing member, and the plug body rotates with the valve stem to achieve the purpose of merging, diverting, reversing, and opening and closing the valve. When the through-hole on the plug body is aligned with the valve body channel port, fluid can pass smoothly; When the plug body rotates and causes the through-hole to be misaligned with the valve body passage port, the fluid is blocked. The three-way plug valves produced by Shanghai Meiyanyi Pump Valve mainly have flange connections and threaded connections, which have the characteristics of low fluid resistance, simple structure, good sealing performance, easy operation, and strong multi-channel adaptability.View details>>

API plug valve
The American standard plug valve mainly refers to the design and manufacturing standards of plug valves based on API6D and API599; The structural length standard follows ASME B16.10; The flange connection standard follows ASME B16.5; The pressure temperature rating follows ASME B16.34; The test and inspection standards follow the API 598 standard for producing American standard plug valves. A plug valve is a type of valve that allows the passage port on the valve plug to communicate or separate from the passage port on the valve body by rotating 90 degrees. The opening and closing components are usually plug bodies with through holes, which achieve opening and closing actions through the rotation of the plug body and valve stem. The structure of a plug valve includes the valve plug, valve body, sealing surface, and other parts. The shape of the valve plug can be cylindrical or conical, and the corresponding channel shape is rectangular or trapezoidal. The structural design of the American standard plug valve produced by Shanghai Meiyanyi Pump Valve makes it easy to operate, has low fluid resistance, and has good sealing performance.View details>>

Rail type plug valve (general valve)
The track type plug valve (general valve) mainly relies on the action of two sealing slides installed on the plug to achieve its specific function. When the plug valve is closed, the slides on the plug will tightly press against the valve seat, forming a seal and preventing the medium from flowing; When the plug valve is opened, the plug rotates 90 degrees, the slide separates from the valve seat, and the medium can flow through the valve. During the opening and closing process of the track type plug valve, there is no contact between the valve body sealing surface and the sliding plate sealing surface, so the sealing surface has no friction or wear, and the valve has a long service life and low opening and closing torque. The application scenarios of the track type plug valve produced by Shanghai Meiyan Yi Pump Valve include pressure levels of 150~900Lb (1.6~32.0MPa), mainly suitable for pipelines such as aviation kerosene, crude oil, light oil, natural gas, liquefied gas, pipeline gas, chemical media, etc., as an ideal device for cutting off media.View details>>

Card sleeve plug valve
The working principle of a sleeve type plug valve is to achieve the opening and closing action by rotating the plug body with the valve stem. Specifically, the sleeve type plug valve uses a plug body with a through-hole as the opening and closing member, and the plug body rotates around the centerline of the valve body to achieve the purpose of opening and closing. The design of the sleeve type plug valve produced by Shanghai Meiyanyi Pump Valve enables the valve to move quickly during opening and closing, with low flow resistance, easy maintenance, and good sealing performance. It is widely used in fields such as petroleum, chemical, natural gas, power plants, metallurgy, and national defense research. The connection and sealing principle is achieved by tightening the nut to apply pressure to the sleeve, causing the blade to bite into the outer wall of the pipe. At the same time, the outer conical surface of the sleeve is tightly fitted with the inner conical surface of the joint, thereby reliably forming a valve seal to prevent leakage.View details>>

Fluorine lined Plug Valve
Fluorine lined plug valve refers to the overcurrent components of a plug valve, such as the valve core coated with PTFE or the valve body lined with PTFE material, which have corrosion resistance, sealing performance, self-lubricating properties, and rotational flexibility. The inner cavity of the fluorine lined plug valve is lined with polymer materials (such as F46, F3), which have strong corrosion resistance and can resist various concentrations of aqua regia, sulfuric acid, hydrochloric acid, hydrofluoric acid, organic acids, strong bases, and other corrosive gases and liquid media. The structure of the fluorine lined plug valve produced by Shanghai Meiyanyi Pump Valve is relatively simple, mainly including the plug body (valve core), valve body, and valve stem. The plug body (valve core) is generally conical or cylindrical, with through holes on it. The valve seat liner (such as polytetrafluoroethylene or para polystyrene) and the steel plug body form a sealing pair, which makes the valve have good sealing performance and a long service life.View details>>

Threaded Plug Valve
Threaded plug valve refers to the connection method of plug valve, which is internal thread connection or external thread connection. Generally, there are more internal thread connections. The structure of threaded plug valve is relatively simple, mainly composed of valve body, plug and packing cover. The valve body has various forms such as straight through, three-way, and four-way. Straight through is used to cut off the medium, while three-way and four-way are used to change the direction of medium flow or distribute the medium. A plug is the opening and closing component of a plug valve, which is cylindrical or conical in shape, and its channel cross-section can be rectangular, trapezoidal, or circular. The threaded plug valve produced by Shanghai Meiyanyi Pump Valve adopts a metal to metal sealing structure, which has excellent sealing performance and basically no leakage. It has a wide range of flow regulation and can generally be used for controlling high flow and high pressure media.View details>>
