Siemens 257-02035 1/2" Pneumatic Valve Assembly 3-8 PSI N/O 1.0Cv FxUM

The Siemens 257-02035 is a 1/2” valve assembly used in HVAC systems. This valve assembly is made of brass and the flow coefficient of this valve is 1. 0CV that effectively controls the fluid flow. The spring range of this valve is 3-8 PSI and it controls the pressure and flow within the system. It is small in size, 1/2”, and can easily fit in any HVAC system. They enhance the performance and reliability of the system as they improve the sturdiness of its control. Fluctuating pressure and flow rates are detrimental to the system and can be wasteful of energy and life shortening to the equipment.
