28mm Mid Position Valve – 3 Port TOWER TFC VAL328MP

Description

The TOWER TFC 28mm Mid Position Valve (VAL328MP) controls water flow in fully pumped central heating systems with precision. This 28mm Mid Position Valve directs flow between hot water, heating, or both at the same time, ensuring efficient system operation.

The valve uses a spring return actuator to switch automatically between positions. When you wire it with a room thermostat, cylinder thermostat, and programmer, it manages the flow from the boiler to deliver the required heating output.

The 28mm compression fittings support higher flow rates, making this valve suitable for larger domestic and light commercial systems. The built-in manual override lever allows easy operation during installation, servicing, or system filling.
