6. Funcionamento
The Zurn Wilkins 34-600XL valve is factory-set to a standard pressure, but it can be adjusted to meet specific system requirements.
6.1 Axuste da presión
- Locate the adjustment screw on the top of the valve.
- To increase downstream pressure, turn the adjustment screw clockwise.
- To decrease downstream pressure, turn the adjustment screw counter-clockwise.
- Use a pressure gauge (not included) installed downstream to monitor the pressure during adjustment.
- Make small adjustments and check the pressure until the desired setting is achieved.
7. Mantemento
Regular maintenance ensures the longevity and optimal performance of your pressure reducing valve.
7.1 Strainer Cleaning
The valve includes a stainless steel strainer to prevent debris from entering the system. Periodically clean the strainer, especially in areas with sandy or debris-laden water.
- Turn off the main water supply and relieve system pressure.
- Locate the separate-access cover for the strainer (typically a cap at the bottom of the valve body).
- Remove the cap and carefully extract the strainer screen.
- Rinse the strainer screen under clean water to remove any accumulated debris.
- Inspect the screen for damage. Replace if necessary.
- Reinsert the clean strainer screen and securely fasten the access cover.
- Restablecer o abastecemento de auga e comprobar se hai fugas.

8 Solución de problemas
This section addresses common issues you might encounter with your pressure reducing valve.
| Problema | Causa posible | Solución |
|---|---|---|
| Downstream pressure too high | Valve adjustment incorrect; debris in valve; worn diaphragm/seat. | Adjust pressure screw counter-clockwise; clean strainer; inspect and replace internal components. |
| Downstream pressure too low | Valve adjustment incorrect; insufficient inlet pressure; debris in valve. | Adjust pressure screw clockwise; check main supply pressure; clean strainer. |
| Water hammer or noise | High inlet pressure; rapid valve closure; air in system. | Adjust downstream pressure; ensure proper valve sizing; bleed air from system. |
| Leakage from valve | Loose connections; damaged gaskets/seals; cracked valve body. | Tighten connections; replace gaskets/seals; replace valve if body is cracked. |
