Description
The Siemens 256-02011 Valve Assembly is a two way normally closed valve for accurate control of fluid flow in HVAC systems. But strongly brasse and can be used dependably between 35°F and 250°F. The valve assembly features a 2″ actuator which responds to pressure inputs, and offers a 1/2″ female connection with Cv of 4.0 and efficiently manages fluid flow while maintaining system integrity. Under that pressure the actuator opens the valve and fluid begins to flow. In contrast, the valve closes to control flow when the pressure is below the setpoint, and opens when the pressure goes above the setpoint.
