VG1245AN+943GGB 1/2 in. NPT 2-Way Ball Valve, 11.7 Cv, with VA9203-GGB-2Z Spring Return Actuator, Normally Closed, Proportional, 24 VAC/DC
Closes on power loss by spring return in about 16 seconds.
Accepts 0(2)-10 VDC directly, or 0(4)-20 mA with a field-supplied 500 ohm resistor, and returns a 0(2)-10 VDC position signal.
Handles hot or chilled water up to 50% glycol, -22 to 212 deg F. Not for steam unless the M9000-561 thermal barrier is added.
Key Features
- Cv: 11.7
- Close-off: 200 psi
- Ball and stem: 300 Series stainless steel
- Torque: 27 lb-in
- Auxiliary switch: one SPDT
