Plug Valves for Reliable Industrial Flow Control

Plug Valve
Plug valves are versatile flow control devices used in a wide range of industrial applications. They feature a durable valve body available in stainless steel, ductile iron, or cast iron, and utilize a quarter turn operation for quick and efficient flow control. With various types of plug valve designs, including tapered plugs and full ported or port design options, these valves handle high pressure and high temperature applications effectively. Often compared with ball valves, plug valves provide reliable performance and precise control, making them suitable for demanding pressure applications across many industries.

A plug valve is a valve that controls fluid flow or regulation by rotating a valve core (plug). Its core structure is simple and provides reliable sealing, making it suitable for high-viscosity, particulate-containing, or corrosive media conditions. It is widely used in industries such as petroleum, chemical, and food processing. MECCO plug valves are designed and manufactured according to API 6D, API 599, GB/T 22130, and other standards, with pressure ratings of CL150, CL300, CL600, CL900, CL1500, CL2500 (or PN16\~PN420).
Size:
NPS1/2~~NPS36 (DN15~~DN900).
Material:
Body material is selected based on customer order; both casting and forging are applicable.
Internal Parts/Stem:
Sealing Surface:
Metal-to-metal (hard seal) or PTFE/elastomer (soft seal). For corrosive conditions, the valve body can be lined with PTFE or rubber as soft sealing materials.
Structure:
Plug:
Tapered plug with straight-through or L-shaped passage, enabling flow control with a 90° rotation.
Valve Body:
Circular or Venturi shape.
Operation Mode:
Manual, gear-operated, electric, pneumatic, etc.

Bellows Seal Valve

Bellows Seal Valve

For applications with extremely strict sealing requirements—such as toxic, flammable, explosive, or highly corrosive media—bellows seals are employed. Both gate valves and globe valves can be designed with bellows sealing. Their design incorporates a dual sealing structure of bellows combined with packing to ensure zero leakage. The previously mentioned standards for gate and globe valves apply here, along with additional reference to bellows valve standards such as MSS SP-117, GEST 89/140, JB/T14315, and JB/T11150.

Needle Valve

Needle Valve

A needle valve is a high-precision valve used for accurate regulation of very small flow rates. Its core design features a slender tapered valve core (needle-shaped) that fits precisely with the valve seat to achieve fine fluid control. It is mainly applied in laboratory instruments, hydraulic systems, gas regulation, and high-precision industrial processes. Domestic design standards include JB/T 7747, or it can be designed according to ASME B16.34 or GB/T 12224.

Knife Gate Valve

Knife Gate Valve

Knife gate valves are widely used in mining, metallurgy, chemical, sewage treatment, and food processing fields. They are suitable for media containing solid particles, fibers, or suspensions, especially for handling slurry, ash, and other complex materials. MECCO knife gate valves are designed and manufactured according to ANSI/AWWA C520, MSS SP-81, MSS SP-135, JB/T 8691, and other standards, with pressure ratings of CL150, CL300, CL600, CL900, CL1500, CL2500 (or PN16\~PN420).

Rotary Ball Valve

Rotary Ball Valve

A rotary ball valve combines the functions and advantages of butterfly valves, segmented ball valves, gate valves, and globe valves, while also possessing its own unique powerful characteristics. Its main structure is similar to a butterfly valve, featuring a compact and short design. Thanks to this structural advantage, rotary ball valves can be manufactured in extra-large and ultra-large diameters to meet the demands of projects of various scales. MECCO rotary ball valves are designed and manufactured according to JB/T 14317 and other standards, with pressure ratings up to PN40 and suitable for temperatures up to 200℃.

Piston Valve

Piston Valve

A plunger valve is a control valve widely used in industrial fields. Its working principle involves a plunger that moves up and down to open, close, or regulate fluid flow. Compared with traditional ball valves and butterfly valves, plunger valves have a simple structure, superior sealing performance, and long service life, making them favored in petroleum, chemical, natural gas, water treatment, and pharmaceutical industries. Domestic design standards include JB/T 12526, JB/T 12954, or it can be designed according to ASME B16.34 or GB/T 12224.

Strainer

Strainer

A filter is a pipeline accessory used to remove solid impurities from fluids, typically installed at the inlet of pressure reducing valves, pressure relief valves, constant water level valves, and other equipment. It protects process equipment and specialized pipe fittings (such as compressors, pumps, fuel nozzles, steam traps, etc.) by preventing debris from entering, which could damage components or clog fittings, thereby ensuring stable process operation and safe production. MECCO filters are designed according to HG/T 21637 and can also be customized per customer-specified standards.
