A pioneer in products for High Performance Liquid Chromatography, Valco continues to offer a diverse line in terms of number of ports, fitting sizes, and materials of construction. 3, 4, 6, 8, 10, 12 port versions are offered, with 1/32" (optional), 1/16", or 1/8" fittings.
Valco valves offer a wide range of rotor and body materials, with alloys and polymer composites capable of meeting virtually any system requirement. However, longest lifetime is provided by our Cheminert coated-stator injectors.
All models can be ordered in manual, pneumatic, or electrically actuated versions.

Air actuators are useful in situations where any spark could be disastrous, where heat could compromise an electric actuator, or where electricity just isn't available.
