	Wide range of optional features and related control equipment
	Feature for feature, the most economical high performance electric actuators on the market CSA approved models

MA-8 85 in. lbs. torque at 2 sec./90 deg.
MAR-8 85 in. lbs. torque at 2 sec./90 deg.

The RCS MA-8 is a unidirectional actuator with an output torque of 85 in. Ibs. for use with 1/4-inch to 1 1/4-inch ball valves. It is available in NEMA 4 and has a terminal strip inside the unit. The RCS MAR-8 is reversible, having a durable high-torque integral single phase capacitor run motor These units are ideally suited for automated and computer controlled systems and will accommodate all of the new RCS solid state controls. Cams, adjustable 0 deg. to 90 deg., are standard.

MAR-10 120 in. lbs. torque at 2 sec./90 deg.
MAR-50 600 in. lbs. torque at 2 sec./90 deg.
MAR-90 1000 in. lbs. torque at 5 sec./90 deg.

These actuators were designed for ball valves from 1 1/4 inches through 2 inches, butterfly valves from 2 inches through 6 inches and plug valves through 3 inches.

The MAR-l 0, MAR-50 and MAR-90 feature the same sturdy construction and high quality of their more powerful counterparts, the MAR-lO0 through -800. These RCS actuators have rugged, high-torque, integral, single-phase, reversible capacitor run motors and are equipped with travel limit switches which are factory set for O deg. to 90 deg. Other settings from O deg. to 360 deg. and multi-turn are available.

All units are ideally suited for automated and computer controlled systems and will accommodate all of the new RCS solid state controls.

MAR-160 1920 in. lbs. torque at 8 sec./90 deg.
MAR-250 3000 in. lbs. torque at 8 sec./90 deg.
MAR-800 10000 in. lbs. torque at 30 sec./90 deg.

Models MAR-l00, -120, -160, -250 and -800 have an electrical lock-out switch to prevent electrical operation while handwheel is engaged.

These units feature rugged, high-torque, integral, single phase, reversible, capacitor run motor Actuators are equipped with travel limit switches which are factory set for O deg. to 90 deg. Other settings from O deg. to 360 deg and multi-turn are available.

All units are ideally suited for automated and computer controlled systems and will accommodate all of the new RCS solid state controls.

These actuators are designed for ball valves 3 inches through 8 inches, butterfly valves from 8 inches through 20 inches and plug valves through 16 inches.
