Challenger Butterfly Valves and Controls offers a complete line of quarterturn electric actuators with output torque ranging from 310 in.lbs. to 31,150 in.lbs. manufactured to 9001 quality standard with both CSA and CE approvals.

Standard features include Nema 4x powder coated aluminium waterproof and dustproof enclosures to IP67, four colour coded switches, heater and thermostat. The non-clutch design manual override with self-locking gear train eliminates the need for a motor brake.

The optional modulating control board features input signal selection of 4-20mA, 2-10 VDC or 1-5 VAC and output selection of 4-20mA or 2-10 VDC. The actuator can be set to fail-close, fail-open or fail in last position upon loss of input signal.
