Solutions provider
Portland Valve Electromechanical Actuator

The Smart Valve EMA provides autonomous damage control of water systems. In case of battle damage, the electromechanical actuator sitting on top of the valves is programmed to identify and isolate ruptured piping in a matter of seconds.
Typical Applications: Fire Protection | Water Cooling

Centrifugal pumps on submarines are used to transport water with very low acoustic noise. The motor turns the impeller driving water through its system.


Pressurization system regulates ambient air pressure around precision instrumentation on military aircraft at high altitude. The inert atmosphere created by this system ensures optimal performance for precision optics and maintains optically clear glass enclosures.

 pneumatic power module

The pneumatic power module is a device that uses stored high-pressure pneumatics to release missiles from aircraft wing bays. The operation consists of first releasing the safety latch which holds the weapon to the aircraft, then pushing the missile with enough force away from the aircraft wing.
