ML6421, ML7421 405 Lbf

ML6421 floating control and ML7421 modulating control 405 lbf Non-Spring Return Electric LinearValve Actuators operate standard Honeywell valves in heating, ventilating, and air conditioning (HVAC)applications.
Overview

The ML6421A,B Non-Spring Return Electric Linear Valve Actuators are suitable for use with low-voltage, single-pole double-throw (spdt),Series 60 two-position and fl oating controllers. These actuators operate standard Honeywell valves in heating, ventilating, and airconditioning (HVAC) applications.The ML7421A,B Non-Spring Return Electric Linear Valve Actuators are modulating control actuators usedwith controls that provide an analog output of 0 to 10 Vdc or 2 to 10 Vdc. These actuators operate standard Honeywell valves in HVACapplications. An internal selector plug can be used to reverse the direction of action.
