this 1 1/4" NPT valve is optimized for controlling air

which comes finished with stripped ends and ferrules for a clean termination in the control cabinet

Precision Voltage: Optimized for an open circuit mV range of 20 to 28 mV to minimize voltage drop issues across the lead

Always verify the rotation by looking at the shaft end or checking the fan blade pitch before completing the install

Siemens Building Technology 192-220 Stat 320788-702 this 1 1/4" NPT valveThe Siemens 192 220 is a professional grade pneumatic room thermostat designed for precision temperature regulation in commercial and institutional HVAC systems. This direct acting (DA), single setpoint controller utilizes a highly sensitive bimetal sensing element to provide proportional control of pneumatic valves and damper actuators. Operating on a 1 pipe system architecture, this unit is engineered for low air capacity applications where a steady
