Siemens 259-02010 2-Way N/C Valve Assembly 1/2" 3-Position 4CV NSR Float 24V

The Siemens 259-02010 1/2" Valve Assembly is a high efficiency control in an HVAC system. This valve assembly features a 4Cv flow coefficient that provides control performance on air and water systems into the highest flow rates.The valve has a 3 position floating action with normally closed (N/C) and spring return (S/R) capability for flexible control options and uses a 24V control signal. It works well in temperatures from 35°F to 250°F and 1.9 pounds. The valve assembly is particularly suitable for commercial and industrial HVAC applications insofar as the flow control accurately and system performance is enhanced. It provides utilities with benefits such as enhanced system efficiency, reliable operation and constant climate control, and that contribute to energy savings as well as better indoor comfort.
