Description
The Siemens 257-02043 1/2″ 2-Way Valve Assembly is a precision designed two way valve assembly for effective fluid control in HVAC systems. This robust stainless steel valve is designed to survive operating conditions. This valve assembly has a 1/2″ diameter and a 4.0Cv flow coefficient, providing effective fluid flow regulation with optimal system performance, and uses a pressure based mechanism. The valve spring is calibrated to a pressure range of 3-8 PSI. The spring applies varying amounts of force on the valve’s internal components as a function of the system pressure and the fluid flow is controlled the 257-02043 is used in HVAC systems to control water flow to something like a heating and cooling coil.
