Hello all,

I'm new colleague in the business, and i'd appreciate if you can help me out. I got some documentation with Siemens Equipment wish is planned for some object. I found all JCI equivalents expect for the following item :
Siemens MVF461H32-12.
Some of characteristics are :
• Short positioning time (<2 s), high resolution (1 : 1000)
• Selectable valve characteristic: Equal-percentage or linear
• High rangeability
• Selectable standard interface DC 0/2...10 V or DC 0/4... 20 mA
• Phase-cut signal input for Staefa controllers
• Position control and position feedback signal
• Wear-free inductive stroke measurement
• Spring return facility: A → AB closed when deenergized
• Low friction, robust and maintenance-free

Link with tech spec is here (http://www.google.com/url?sa=t&source=web&cd=1&sqi=2&ved=0CBUQFjAA&url=http%3A%2F%2Fwww.sbt.siemens.ru%2Ffiles%2F1303 9.pdf&rct=j&q=MVF461H32-12&ei=RynBTb_vG5GcOrXL1Z0I&usg=AFQjCNG2zxzcScHhfMl3NGEKPgu61jxswQ&cad=rja)

Can any1 help me out, what's JCI equivalent for this ? Tricky part is position time <2s. It's used for installations with steam.

Thank you in advance!

I like magnetic actuators - High resolution, low hysteresis, compact, fast response, etc., etc.

I do not know if JCI markets a magnetic actuator - I suggest you contact them.

What is the application, what are the valve requirements, and why is it important to have JCI??
