Description
Siemens Building Technology 267-05991 3″ N/C NSR Valve 100Cv 125 Bronze regulates liquid flow by remaining closed until a 24-volt signal initiates valve movement within HVAC systems. The internal actuator responds to electrical input by repositioning the valve mechanism, allowing the passage of water through the connected piping as operating conditions require. Its bronze body provides a durable flow path, while the internal sealing components maintain positive shutoff when the signal is removed. Connected to compatible hydronic equipment, the assembly maintains accurate flow management and stable circulation during heating and cooling operation.
