Micro Valves

Since its introduction in 1956, the Micro Valve has provided successful service through thousands of applications. Choose Micro Valve, 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.

 

Quick, Sure Response with Design Adaptability  

With a unique, over-center snap-action, you get 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. All models have been tested through several million cycles without maintenance, thus guaranteeing your systems' performance.

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.



Dependable Performance  

The 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.
