EA50 and EA60 Standard Series Medium

Torque Non-Spring Return Rotary Actuators

6-12

Features

• proportional actuators w/ built-in feedback potentiometer

• open/close contact closure input

• 24Vac, 120Vac and 240Vac

• 60, 220 and 450 in-lbs torque

• compatible with VB series valves

The EA50 and EA60 medium torque actuators are ideal for proportional positioning of a fuel valve, butterfly valve, damper and similar applications. Units are available with either fixed or adjustable speed. Timing of adjustable speed units can be increased (decreasing the speed) by turning a slotted adjustment screw on the outside of the case. Adjust range is approximately ten times rated.

Standard features include a 100Ω feedback slidewire and a single SPDT switch.

All models, except those with transformers, are UL/cUL listed. The EA50 and

EA60 are compatible with the VB-7000 and VB-9000 valves in this catalog.
