Non-spring return direct-coupled Valve Actuator with 135 lbf rated force

Overview

The Non-Spring Return Electric Linear Valve Actuators have floating or modulating control. These actuators operate standard Honeywell valves in heating, ventilating, and air conditioning (HVAC) applications. Floating control actuators are used with controllers that provide a switched or floating single-pole double-throw (SPDT) output. Modulating control actuators are used with controllers that provide an analog output of 0 to 10 Vdc or 2 to 10 Vdc.

Features

• Easy and quick installation on valves with 1 3/8 in. bonnet and 3/4 in. stroke
• No separate linkage required
• Conduit connector standard
• No adjustments required on linkage.
• Accurate valve positioning
• Low power consumption
• High close-off ratings
• Force limiting end switches
• Manual operator
• Synchronous motor
• Maintenance free
• ML7420 has an internal selector plug that can be used to reverse the direction of action.
