Description
Siemens’ 256-02070A is a brass 3 way mixing valve for use in HVAC systems that can control flow of fluids precisely. This unit is constructed with brass and can hold temperatures from 35°F to 250°F making it a unit for various HVAC applications. The valve is a three way valve that combines two fluid streams (usually hot and cold water) to give the desired temperature output. The valve position is maintained by a pneumatic actuator that varies the flow of each fluid to keep the setpoint constant, and is controlled by a thermostat or other control device, widely used to regulate water in heating and cooling systems, such as fan coil units, radiant floor systems, and terminal units.
