What it is

The Coster MAS 620 is an electronic mixing valve with a 3/4" connection, manufactured by Coster. It blends flow and return water electronically rather than by a mechanical thermostatic element, so the mixed water temperature is set and held by the valve's control electronics. It is intended for heating and hot water circuits where a controlled mixed temperature is required.

Before you order

  • Confirm the 3/4" connection matches the pipework or fittings at the installation point.
  • Check the mounting position and the space available around the valve body for access and servicing.
  • Review the manufacturer's documentation for the control signal and wiring requirements of the system it is being fitted to.
