VA-908x Series Electric Rotary Actuator for Two-Position and

Modulating Service Mounted on a VF Series Butterfly Valve

Issued August 24, 2009

VA-908x Series

VA-908x Series Electric Rotary Actuators for Two-Position and
Modulating Service

Description

The VA-908x Series Electric Rotary Actuators for Two-Position and
Modulating Service are designed for direct mounting in an upright
position on VF Series Butterfly Valves. The VA-908x is available in two
different sizes, for two-position and modulating service.

All models feature two independently adjustable, travel limit switches
for the open and closed position, each factory-set for 90° valve
rotation. Powered by a rugged, high-torque, single-phase reversible
motor, the VA-908x actuators are designed to withstand stall torque for
reliable performance in even the most demanding applications. The
watertight actuator enclosure meets National Electrical Manufacturers’
Association (NEMA) 4, 4X, and 6 ratings, as well as IP67 standards.

Refer to the VA-908x Series Electric Rotary Actuators for Two-Position
and Modulating Service Product Bulletin (LIT-12011565) for important
product application information.
