The jacketed plug valve features a sealing surface with a wiping effect during movement. In the fully open position, it prevents contact with the flow of media, making it ideal for use with media containing suspended particles. A metal jacket is installed within the valve body, through which steam, heat-conducting oil, cooling water, cool air, or other fluids can be injected. This allows for precise temperature control, heating, cooling, or maintaining the required temperature within the valve body.

Full Port Steam Jacketed Plug Valves are especially effective for handling high-viscosity, steam, or other media that require temperature regulation to remain in a flowable state. This ensures the medium can flow normally through the valve, preventing solidification at room temperature and ensuring proper operation under heat preservation or cooling conditions.

Product Features

Zero leakage: With primary sealing by sleeve (lining in case of lined plug valve), secondary sealing by diaphragm and tertiary sealing by wedge ring, the plug valve assures zero leakage of the fluid flowing through the system.

Secure sealing: The sleeve is positively locked in the body with the locking ribs located in the body to assure secure sealing.

Cavity free: There are no cavities in the body, the plug is surrounded completely by sleeve, so there is no possibility of fluid accumulation and contaminate feature processing. This cavity-free design also prevents sticking.

Non lubrication: The PTFE sleeves have a low coefficient of friction and acts on a lubricant. Hence ease of operation is assured even though valve unopened for a period.

Low maintenance: The sealing pressure can be regenerated by the adjustment bolts provided on the cover without disassembly for repair. On line repair is easy as the plug is top entry type which will reduce the shutdown time of the plant.

Superior in line sealing: The plug is completely surrounded by the sleeve, providing a large circumferential sealing surface from port to port.

Self cleaning: As the plug rotates, the port lips located throughout 360° provide a self cleaning action to remove stealing and adhering media, facilitates no seizing and no sticking.

Adjustable sealing: When seal presence adjustment is required due to sleeve wear, slight rotation of adjustment bolts pushes the plug downwards thereby providing extra sealing pressure.

Antistatic electricity: Static eliminator (only in case of sleeved plug valves) is always in contact with the plug and releases the static electricity generated from the free floating fluid to the pipeline.

Compact design: Taper plug with trapezoidal shaped port, one-piece body and less number of parts required to construct the valve make a compact and cost-effective plug valve.
