Prepare a Q22HD valve inquiry
Start with the complete model or nameplate reference, the current drawing or datasheet, and the intended service. Ask the supplier to identify the exact configuration on the quotation.
Details to confirm before ordering
| Question | Information to supply or request |
|---|---|
| Medium and temperature | Composition, concentration, normal and maximum temperature, plus cleaning fluids |
| Pressure and flow | Inlet/outlet pressure, transients, required flow and allowable pressure drop |
| Connection and size | Port or flange standard, installation dimensions and drawing revision |
| Body and wetted parts | Exact alloy or grade, seal material and any material restrictions |
| Actuation | Available pilot supply, operating sequence and behavior when supply is lost |
| Leakage and duty | Required shutoff performance, cycling conditions and agreed acceptance test |
| Documentation | Model-specific datasheet and any required certificate or test-report scope |
Existing EMC document
The published EMC verification document, number CEZJ23090550357, includes Q22HD in its model list. It is dated 7 September 2023 and shows an expiry date of 6 September 2028. The listed EMC scope does not establish a pressure rating, material specification or hazardous-area approval.
Hazardous areas and restricted materials
Pneumatic actuation alone does not establish suitability for a hazardous area. State the area classification and applicable project requirements, and obtain the documentation for the complete assembly. Avoid treating an air-operated valve as inherently explosion-safe.
If lead content, potable-water use, steam, fuel gas or another regulated service matters, state that requirement explicitly. Request the material declaration and model-specific suitability evidence before approving the configuration.
Samples, timing and quotation
Provide the quantity, destination, required delivery date and inspection requirements. Confirm MOQ, sample availability, charges and delivery timing in the written quotation.
For a replacement, include clear nameplate photographs and installation dimensions. Identify which performance requirements must be retained and which changes are permitted.
