Jet-Pipe Servovalves

The Moog Atchley Controls line of jet-pipe servovalves from Moog Inc., Industrial Controls Div., East Aurora, N.Y., consists of hydraulic and pneumatic servovalves, as well as pneumatic-feedback actuators. The servovalves are recommended for dirty working environments such as metal-forming, wood-processing, and underwater-vehicle applications. Features include a jet-pipe design to prevent fluid contamination, a single-orifice jet, high recovery pressure, and feedback wire attached to a spool. Rated flows range from 0.25 to 180 gpm at 1,000-psi valve drop.
