Record the full valve requirement
Provide the connection type, material, pressure class and any actuation or control requirements. Include the fluid and operating conditions. For automatic filter valves, identify the vessel arrangement and operating modes. A visually similar replacement may have different internal functions or connections, so compare documentation rather than photographs alone.
Valve function, connections and ratings must all match
Water-treatment valves can serve different functions, including routing a filter cycle, isolating a line or controlling a process duty. Identify the actual function before comparing size. Provide fluid, pressure, temperature, material and connection requirements. Automatic operation may also involve an actuator or control arrangement that needs to be included in the compatibility review.
| Requirement | What to compare | What to confirm |
|---|---|---|
| Filter valve | Review the required operating modes | Match vessel connections and internal arrangement |
| Softener valve | Review service and regeneration functions | Match the actual resin-system configuration |
| Other flow-control duty | Review the function and ratings | Confirm fluid and control compatibility |
A selection mistake to avoid
A valve that fits a pipe connection may still have the wrong function or limits. Compare the complete specification before ordering.
What helps distinguish a filter valve from a softener valve?
The documented operating modes and connection arrangement. Use the model identity and system requirements rather than assuming that similar housings are interchangeable.
Planning the enquiry in Sabah
SWFI’s catalogue includes industrial and water-treatment valve categories. Send the brand, model, part number and nameplate or clear photographs for a replacement enquiry. State the quantity and project location. Confirm any accessories or control components included in the supply so the installation team receives the complete agreed scope.
Information to prepare
- Duty, fluid and operating conditions
- Size, connection, material and rating
- Model identity and control/accessory requirements
Can a valve be replaced using pipe size only?
No. The operating duty and complete specification must also be checked, including function, connections, ratings and controls.
