The Automatic Back-flushing System 4-way valve uses reversed water flow to clean the plates while the heat exchanger remains on-line.
How it Works
The four-way valve automatically reverses water flow in the heat exchanger for about 30 seconds, Once every 6 hours. The valve fits into the supply and return piping and is custom manufactured to suit any piping configuration.
The Automatic Back-flushing System Control panel consists of a 24-hour timer, a back-flush relay to control how long the valve remains in reverse flow, a cycle counter and a malfunction indicator.
