Siemens 171D-10322 1.5" 2-Way Ball Valve Assembly 25Cv NSR Proportional

Siemens 171D-10322 is a high performance 2 way ball valve assembly for proportional control in HVAC systems. This valve has a 1.5" diameter and a 25 Cv flow coefficient and efficiently controls huge amounts of fluid. Made of robust brass and with NPT connectors for easy integration into existing systems it is going to last. Within this temperature range of 35–250°F the device operates and meets the ANSI Class IV pressure regulations for a variety of situations. The heating and cooling is controlled with an actuator operating at 24V that provides accurate proportional control. The Siemens 171D-10322 greatly enhances system performance with accurate flow regulation and energy efficiency as well as proper operation in highly complicated HVAC systems.
