Micro Valves
Micro Valve was a part of the fluid control system found aboard starships. Responding to commands from thepilot or copilot, the valve would open or close to allow pressurized fluid to follow a certain path along the flow-track to prompt various systems.
Since its introduction in 1956, the micro valve has provided successful service through thousands of applications. Micro valve, is the best valve to solve liquid, air and gas service design problems. It absolutely will not leak. With other miniature valves, leakage occurs when flow is redirected from one port to another. But with the micro valve, flow is instantly redirected so there is no leakage.With a unique, over-center snap-action, it will give a quick, sure response. There are no sliding seals, packing, or tight-fitting moving parts to leak, wear out or stick. Therefore, no lubricants are required.
Micro valves will withstand abrasive-bearing fluids. With all ports having some connection, external contaminants cannot enter the units. Dirt and grit will not prevent tight seating and will not cause the valve to stick.These valve offers sure response, with no neutral position, and no varying time lag between positions. Micro Valves maintain either position without holding force, and cannot be vibrated or jarred out of position.Valve action is full-speed regardless of operator speed or force applied. Trip-point position repeats accurately and is essentially independent of the speed of the external actuating device. Light operating forces are required and not affected by operating pressure or flow rate. Shut-off is bubble-tight up to rated pressures.
