Siemens 257-02069B 1/2" 3-Way Mixing Valve Assembly FEM X FEM 4.0Cv 3-8 PSI

The Siemens 257-02069B is a 1/2” 3-way Mixing Valve Assembly used in HVAC systems. This type of valve has Flow Coefficient of 4. 0CV and is designed to work within a spring range of 3 to 8 PSI which makes it easy for the modulation of the flow rates. Made of brass, this valve is rather durable and can be used in high-stress environments. This 3-way valve operates through the mixing or bypassing of fluid streams in a bid to ensure efficiency within the system. It is mostly applied in HVAC equipment including boilers, chillers and fan coil units where there is need to control temperature and flow rate.
