PFT Solenoid Valve – Water Control for G4, G5 & Ritmo

Control water flow accurately and reliably with this replacement solenoid valve for PFT plastering machines.

The solenoid valve is a critical component in the water control system, opening and closing automatically to regulate water entering the machine. If the valve fails, water control is lost — leading to over-watering, poor material consistency, and machine faults.

This listing offers multiple solenoid valve options, including a block-only replacement, allowing you to repair the valve without disturbing the brass body already fitted to the machine.

🔧 What the Solenoid Valve Does

• Opens and closes the water supply automatically

• Controls correct water dosage into the machine

• Responds to machine control signals

• Prevents unwanted water flow when switched off

🔁 Block-Only Replacement Option (Important)

The block-only option allows you to replace all working internal components of the solenoid valve — including:

• The electrical coil

• The membrane / sealing mechanism

• The internal valve assembly

✅ No need to remove or disturb the brass valve body
✅ Ideal if the brass section is in good condition
✅ Faster repair with less pipework disturbance

This is the preferred option when the valve has failed internally but the brass housing is still serviceable.

⚠️ Common Failure Causes

• Dirt or grit passing through unclean water filters

• Debris preventing the valve from sealing fully

• Worn or damaged membrane

• Electrical coil failure

👉 Many solenoid issues are caused by contamination. Regular filter cleaning is essential to prevent valves sticking open.

💡 Before Replacing the Full Valve

• If the solenoid is stuck open or leaking, a membrane repair kit may be sufficient

• If the coil or internal mechanism has failed, the block-only replacement restores full function

• Replace the complete valve (including brass) only if the body is damaged or seized

🔩 Compatibility

Suitable for solenoid valves fitted to:

• PFT Ritmo

• PFT G4 (all variants)

• PFT G5

🛠 Installation & Maintenance Tips

• Isolate water and power before fitting

• Clean inlet filters before installing any new solenoid parts

• Flush water lines if contamination is suspected

• Regular filter maintenance greatly extends solenoid life
