NEFA Valves
Nefa valves are designed primarily for use in domestic water supply installations. The purpose of the valves is to supply debris free water at a controlled pressure and temperature, with some valves working while others are primarily there for safety.
Valves: High Pressure - Low Pressure - All Pressure - Mains Pressure / Low Pressure Kits
NEFA High Pressure Valves:
Mains Pressure Inlet Control Valve 4-in-1 Isolation, Filter
