    Little help

    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

    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??
