Four-way mixing valves

A four-way mixing valve is used for mixing hot and cold water to achieve the ideal fluid temperature in the distribution systems. They allow for a two-inlet and two-outlet mode, or three inlets and one outlet. Four-way valves have a dual mixing function: they mix hot water from the boiler with returning water from the radiator circuit, resulting in water of a higher temperature flowing into the boiler, thus protecting the boiler from low-temperature corrosion. Four-way valves are made from brass with protection against zinc leaching, or cast iron, and are used in heating and cooling systems, water distribution, heating applications, and mixing systems. They can be controlled in three ways: manually with a dial, with a thermostatic cartridge, or with an actuator, for which the correct adapter is required for installation. All main components of mixing valves can be easily replaced, however, we recommend installing a suitable filter in the system before the valve. This will prevent the need for more frequent maintenance of the four-way valve, extend the lifespan of the valve, boiler, and distribution systems, and prevent excessive wear or potential damage due to a higher amount of mechanical impurities in the water.
In heating applications and distribution as well as mixing systems, modern four-way mixing valves have proven to be excellent. The valve body is most commonly made of brass, ensuring high quality and long product durability thanks to DRZ protective treatment against zinc leaching. These valves are generally found primarily in heating and cooling systems, with the dual mixing function allowing a portion of the hot water, which is supplied from the boiler, to be mixed with the return water from the radiator circuit. This serves to ensure a higher water temperature entering the boiler. The four-way mixing valve includes a control wheel with a clear scale. The rotation range for these types of valves is "all around," meaning there are no end stops. The scale can be set to any position as needed. If it is more advantageous to control the mixing valve via an actuator, the valve can be adapted with a simple installation of a suitable adapter. In addition to ESBE actuators, Belimo actuators can also be used for most types. Connecting four-way mixing valves into the circuit is done via internal or external threading on the valve body, or you can choose a flanged variant. The body of mixing cocks with flanges is made of grey cast iron. We offer a wide selection of four-way valves from the reliable manufacturer ESBE
