Stem up on power failure direct-coupled Valve Actuator with 135 lbf rated force

Overview

The ML6425 Spring Return Electric Linear Valve Actuators are floating control actuators used with controllers that provide a switched or floating single-pole double-throw (spdt) output. These actuators operate standard Honeywell valves in heating, ventilating, and air conditioning (HVAC) applications. The ML7425 Spring Return Electric Linear Valve Actuators are modulating control actuators used with controllers that provide an analog output of 0 to 10 Vdc or 2 to 10 Vdc. These actuators operate standard Honeywell valves in heating, ventilating, and air conditioning (HVAC) applications. An internal selector can be used to reverse the direction of action.

Features

• 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
• Internal manual operator
• Synchronous motor
• Maintenance free
