PFT Solenoid Repair Kit Membrane/Housing – Repair Kit for G4, G5 & Ritmo

Restore correct water control without replacing the full solenoid valve.

This replacement solenoid membrane kit is designed as a cost-effective repair solution for solenoid valves fitted to PFT plastering machines, including the PFT Ritmo, PFT G4, and PFT G5.

In many cases, solenoid valves fail not because the coil is faulty, but because dirt or grit becomes trapped on the membrane, preventing the valve from sealing correctly. This causes the valve to stick open, leading to uncontrolled or constant water flow.

Replacing the membrane restores the seal and function — saving the cost of a full solenoid replacement.

✅ Common Symptoms This Fixes

• Water flowing when it should be shut off

• Solenoid stuck open

• Inconsistent or uncontrolled water supply

• Machine flooding or over-watering material

🧠 Why Solenoids Fail

Solenoid valves on plastering machines rely on clean water. If filters are not cleaned regularly, dirt can:

• Lodge between the membrane and valve seat

• Damage or distort the rubber diaphragm

• Stop the valve from closing fully

👉 This is why cleaning water filters is essential maintenance on all PFT machines.

🔧 Product Features

• Replacement rubber membrane / diaphragm

• Designed to repair the internal sealing function

• Alternative to replacing the complete solenoid valve

• Quick, straightforward repair for experienced users

• Ideal spare to keep on the van

🔩 Compatibility

Suitable for solenoid valves fitted to:

• PFT Ritmo

• PFT G4 (all variants)

• PFT G5

⚠️ Always confirm membrane shape and size against your existing solenoid before fitting.

🛠 Recommended Maintenance

• Regularly clean the water inlet filter

• Flush water lines if contamination is suspected

• Inspect membrane during servicing

• Replace membrane if water does not shut off fully

Preventative maintenance massively extends solenoid life.
