Carleton designs and manufactures pneumatic devices required for pressure control. Our products include pressure regulators, check valves, relief valves, and automatic stop valves that meet stringent U.S. Navy specification requirements.

Carleton designs and manufactures a wide range of products used in oxygen gas systems to strict Level I requirements. These include oxygen stop valves, oxygen reducing manifolds, oxygen regulators, oxygen relief valves, oxygen check valves, and flow control valves.

Typical oxygen products in this marketplace include:

	Manual Valves All U.S. Navy nuclear submarines contain 3000psi oxygen systems for life support. Carleton supplies a variety of military specification 1 manual valves to control the flow of high-pressure oxygen throughout the system. Carleton manual valves are used on all U.S. Navy nuclear submarines.
	Oxygen Pressure Reducing Manifold The 3423-0001 series manifold is an Oxygen Pressure Reducing Station Assembly installed on many U.S. Navy Submarines. This manifold provides integrated control of pressure and flow to a breathing apparatus installed at the outlet port.
	Mechanical Actuators U.S. Navy nuclear submarines store high-pressure oxygen outside the pressure hull. The high-pressure oxygen is brought into the submarine through a hull penetration tube welded into the bulkhead. Emergency situations sometimes require the oxygen supply to be turned off from remote locations. Carleton's lanyard operated mechanical actuator is mounted on top of the hand valve and is used to remotely shut off the oxygen supply.
	Oxygen Generator Valves All U.S. Navy nuclear submarines use an electrolytic oxygen generator (EOG) to convert water into oxygen and hydrogen gases. Carleton's valves are used to control the flow of water, hydrogen and oxygen through the generator.
