Remote Valve Actuators

Problem: Current electro-hydraulic and electro-pneumatic actuators suffer from very low reliability and are maintenance intensive. New, all-electric devices with high torques are now available, but unproven in shipboard applications.

Solution: MTTC, in conjunction with COMNAVAIRLANT and AMSEC, obtained and tested actuators from Tri-Tec, Inc., and Limitorque, Inc. on USS GEORGE WASHINGTON and USS THEODORE ROOSEVELT.
