Description
The Siemens 254-01105 1/2″ 2-Way Valve Assembly N/C Brass is a small and efficient two way valve assembly of brass. It is used with HVAC systems and controls the flow of water or some compatible fluid. Normally closed (NC) means the valve blocks flow until an electrical signal activates it and its 1/2″ size and 1.0 Cv flow coefficient make it suitable for a range of applications the valve’s operation is simple. The internal actuator overcomes the spring force when powered by 24 VAC This two way valve is used widely in HVAC systems including hydronic heating, cooling, and fan coil, and this electrical controllability gives accurate flow regulation, which is critical for maintaining peak system performance.
