Schneider Electric Electric Valve Actuator -, 24 V ac Supply Voltage

The AVUEs (795-9448 and 795-9457) are modulating actuators having a linear output drive; they can be used in conjunction with any controllers providing a 0-10Vdc output signal to operate Satchwell VEU, MEU, FEU, VZX and MZX valves. The short stroke (9.5mm) versions (both direct and reverse acting) are compatible with VEU (Mk 4) 2-port, MEU (Mk 4) 3-port and FEU (Mk 5/6) 4-port control valves. The long stroke (12.7 mm) versions (both direct and reverse acting) are compatible with VZX 2-port and MZX 3-port valves. All these control valves are applied, typically, to regulate the flow of either hot or chilled water supplying heating or cooling coils in various types of terminal unit, for example fan coil units, reheat coils associated with variable air volume units, also small air handling plants and heat exchangers.

The AVUX (795-9451) is a 24Vac modulating linear actuator suitable for modulating compatible Satchwell valves from any 24Vac, 3-point controller or device. The AVUM (795-9479) is a mains voltage (230Vac) modulating linear actuator which can be controlled from any controller or device having a 3-point mains switched output. Both the AVUX and the AVUM valve actuators are suitable for use with VEU (Mk 4) 2-port, MEU (Mk 4) 3-port and FEU (Mk 5/6) 4-port valves, also the VZX 2-port valve and the MZX 3-port valve.
