Note

ML7421A8035 can be used up to a max 3'' valve only

What is a Modulating Control Valve?


A modulating control valve is an automated valve that is used to control the amount of flow in a system or process. They go beyond simple shutoff or isolation (on/off) and actually allow precise control of the flow rate. The actuators on these valves use feedback and control signals to accurately open and close the valve. 


Note
1) ML7421A is for big valve.Torque is 1,800Nm. ML7420A8088A is for 1.5'' and below. Torque is 600Nm.
2) Pls note that there is no performance warranty on ML7420A with V5011P1038 (2'' 2-Way). It may not be strong enough to close the valve after a while.
3) All modulating actuators/thermostats are automatically 24Vac. This is industry standard.

 V5329A/ML7421A- 3'' 3 Way valve c/w mod actuator
 V5328A/ML7421A - 3'' 2 way valve c/w mod actuator

New Combination With New Valve Types

The valve for 3'' 3-Way is V5GV3W080F and the valve for 2-Way is V5GV2W080F. You can still use back the same ML7421A Actuator
 

GENERAL
 
The ML7421A / ML7421B actuators are designed for modulating control, accepting 0(2)...10v or 4...20mA input
signal, and providing feedback signal 2...10 Vdc only. They operate Honeywell’s standard valves in heating, ventilation,
and air conditioning (HVAC) applications.

FEATURE
 
 Easy and quick installation
 No separate linkage and adjustments required
 Low power consumption and maintenance-free
 Self-adaption function
 Force-limiting end stops
 Manual operation knob
 0(2)~10 Vdc input and 2~10 Vdc position feedback
 Direct/ Reverse action adjustable
 Selectable stroke position when signal failure
 Corrosion-resistant design
