The MINIMIX MI 4-way valve is a compact mixing valve made of cast iron for use in heating installations. 3-way valves are typically used to mix supply water from a heat source with water returning from a system. 4-way valves additionally are saving boiler against too low temperature of water returning from a system. They are designed for use in either closed loop or open loop. To operate the valve in full auto mode it is necessary to install an actuator.
