Moog offers the broadest line of Electrohydraulic Valves on
the market today. Our product line consists of Servovalves
(Mechanical and Electric Feedback versions) and Servo-
Proportional Valves (Direct Drive and Two Stage ServoJet
®
versions). Servovalves typically utilize a ISO10372 mounting
pattern and are nearly always zero lapped or axis cut (no
mechanical deadband). Servo-Proportional Valves utilize an
ISO4401 mounting pattern and may have a mechanical deadband.
Selection of the proper valve involves understanding the
performance requirements of your application.The chart below
attempts to categorize the more popular Moog valve series by
two very important selection criteria – flow and dynamic response.
