- Ngabersihan hawa: Open faucets throughout the system to purge air until water flows smoothly.
Operasi
The Watts LF26A valve is factory preset to a nominal pressure. Adjustment may be necessary to achieve the desired system pressure.
Nyaluyukeun Tekanan Outlet:
- Ensure a pressure gauge is installed downstream of the valve for accurate readings.
- Ka naékkeun the outlet pressure, turn the adjustment screw (located on top of the valve) saarah jarum jam.
- Ka ngurangan the outlet pressure, turn the adjustment screw counter-jarum jam.
- Make small adjustments (e.g., quarter turns) and observe the pressure gauge. Allow the system pressure to stabilize after each adjustment.
- Once the desired pressure is set, ensure the locknut (if present) is tightened to secure the setting.
The adjustable pressure range for this model is 1 to 25 psi.
Pangropéa
Regular maintenance helps ensure the longevity and optimal performance of your pressure regulator valve.
- Inspeksi taunan: Annually inspect the valve for any signs of leaks, corrosion, or external damage.
- Verifikasi tekanan: Periodically check the outlet pressure using a pressure gauge to ensure it remains at the desired setting. Fluctuations may indicate a need for adjustment or service.
- beberesih: The exterior of the valve can be wiped clean with a damp cloth. Do not use harsh chemicals. Internal cleaning or servicing should only be performed by a qualified professional.
- Winterization: In areas subject to freezing temperatures, ensure the valve and associated piping are adequately protected from freezing. Drain the system if it will be out of service for an extended period in freezing conditions.
