Buyer selection checks
How should buyers specify a lubricated plug valve?
The existing KEHUA catalogue identifies this as a lubricated plug-valve series for oil and gas isolation. Confirm the offered model's lubrication arrangement and service limits before approving it for a particular fluid or line specification.
What lubrication information belongs in the enquiry?
State the fluid, operating and design temperatures, pressure conditions and operating frequency. Ask the supplier to identify the proposed lubricant, its service compatibility and the maintenance or injection access required for the offered design; these details are not confirmed by the series name.
Which documents should be checked before ordering?
Request a model-specific datasheet and drawing showing the required size-rating combination, connections, materials and operation. Identify the inspection and document scope in the RFQ. A family-level range does not confirm every size or pressure combination for this series.
Missing model data stays pending. Send the known conditions for this lubricated plug valve.
