Truck heater control valves: an OE-led wholesale buying checklist
Use DAF and Scania catalog examples to request the missing hose, mounting and electrical details before a bulk heater-valve quotation.
A heater-valve photo can look convincing while leaving the important purchasing fields blank. SAP-D301 lists DAF references 1672648 and 1935413. SAP-S300 lists Scania references 1793197 and 1741027; SAP-S301 lists 1787393. These are separate catalog entries. None of their current notes supplies a hose diameter, voltage or flow specification.
Compare the actual catalog records
These are current catalog examples, not an approved substitution list. OE references and remarks below are reproduced from the supplied records; they do not establish compatibility, stock or electrical performance.
Editorial note: this purchasing guide was prepared with AI assistance using the supplied catalog and document-coordination scenarios. It is not a product test, technical approval or a promise of SHIRE order terms.
Start with the original assembly reference
Keep the original marking and the candidate catalog OE separate. Include the vehicle or assembly information available to you and photos of the installed orientation where safely obtainable. A DAF or Scania application label does not establish compatibility with every vehicle from that brand.
Request a dimensioned connection view
Ask the supplier for the port arrangement, connection dimensions and mounting details of the exact offered valve. Include your required hose interface and installation space if known. Do not estimate dimensions from the website image or assume two similarly shaped valves share the same connections.
Leave undocumented specifications open
Ask for electrical connection details and applicable operating specifications where required. Mark missing fields as unconfirmed in the RFQ. The empty remark on these three records is not evidence of a mechanical-only design or a particular voltage. Technical compatibility and any functional test require appropriate supplier documentation and qualified assessment.
Quote the confirmed version
Once identified, request a line price for the accepted SKU, quantity, sample requirements, packaging and destination. Keep any proposed alternative on its own line with the reason for substitution. Use the product records below to start the discussion; they are not claims of interchangeability, pressure-test results or available inventory.
Purchasing guidance, not installation or diagnostic instructions. Confirm compatibility and specifications with the supplier and a qualified technician.
