MOOG D671 and D672 series servo valves are used to control position, velocity, pressure or force. this series has very good static and dynamic properties and is ideal for high performance machine applications.
Moog servo valves feature a spool sliding in a bushing offering better accuracy, compared to a spool sliding within a cast-iron body. the advantages of this design are:
The highest precision positioning and control due to expert design and manufacture of the spool lands and slots
Customer specific ?ow characteristics due to the availability of a tailored design geometry of slots in the bushing.
MOOG D671 series servo valves in size 05 are a 2-stage design with a servoJet® pilot stage. two pilot stage versions with different ?ows are offered to meet different dynamic requirements.
The servoJet® standard meets typical requirements and offers lower leakage ?ow.
The servoJet® high flow provides higher dynamic response.
MOOG D672 series servo valves in size 07 are a 3-stage design with the 2-stage servoJet® pilot valve D670. The 3-stage design offers the highest dynamic response and provides a stable spool control even for the most demanding applications.
this valve series features digital on board electronics offering the user high ?exibility, and an embedded microprocessor enabling very fast processing speeds. The Moog valve configuration software is used to easily tune the valve performance, change parameters and perform diagnostics, all through a service connector.
