Pallas FX TW150 is a Twin Valve, meaning that it’s a single control head valve designed for operation with two tanks. When one tank is in service, the other is placed either in standby or is regenerating. This allows for a continuous supply of soft water. It is designed for residential and commercial applications requiring flow rates up to 12.0 m³/h (peak) and it has a backwash ability capable of servicing up to 30″ diameter tanks.
 
The valve is controlled by a solid state microprocessor with front panel setting and screen display. The FX TW150 has 2 injector sizes to choose from for different draw rates.
