What type of globe valve are you automating? A control style globe valve like a Fisher? Or are you doing a cast steel globe valve like a Crane/Powell/Velan?
We've supplied a lot of ABZ valves to customers for a variety of applications, and haven't had any issues. ABZ's ABZolute Series HP valves (which the 402 falls under) are manufactured in South Korea and we've had good success with them in both manual and automated applications. If you're...
What is the valve thrust? Do you have any of the valve data? Size, manufacturer, rising stem or non-rising stem, etc.? You really should have stem dimensions to determine the stem factor - this will allow you to more accurately predict the torque required.
The thrust base plates on multi-turn electric actuators have an upper limit. Where the thrust force is taken is another matter. If there is a thrust plate on the valve that takes that thrust force, your actuator will only see torque. If the actuator drive bushing is taking the thrust, then...
