Siemens 257-02042 1/2" 2-Way Valve Assembly Brass FxUM NO 4Cv 3-8 PSI

The Siemens 257-02042 is a 1/2" 2-Way Valve Assembly which is rugged and performs well and suitable for applications that require precise control such as HVAC systems. It is a brass material valve and has the flow coefficient of 4. 0CV, which make it possible for it to well manage the flow of the fluids. It operates between a spring range of 3 to 8 PSI thus it is effective once it is put under different pressures. In HVAC equipment the valve functions to either regulate or divert the flows of water or the other fluids in heating and cooling equipment.
