- Viscous media
Buyer selection checks
What must be specified for a jacketed plug valve?
The KEHUA catalogue identifies a jacketed plug-valve series for viscous-media enquiries. Specify the process fluid and proposed jacket service separately so the supplier can review the offered assembly; do not assume the jacket shares the valve body's rating.
Which conditions belong to the process and to the jacket?
For the process, state the fluid, viscosity or flow behaviour where known, operating and design pressures and temperatures, and size. For the proposed jacket circuit, identify the medium, required temperature, pressure and connections. Confirm the offered jacket's limits and coverage on its drawing.
What installation and maintenance details need review?
Send the piping layout and identify clearance, jacket inlet and outlet positions, insulation and access requirements where defined by the project. Request the final body, seat and seal materials and the exact size-rating combination. Do not assume a heating medium, temperature capability or jacket configuration that is absent from the model datasheet.
