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.

Manual actuation offers the advantages of simplicity and low cost.
An optional position feedback is available for manual Valco W and UW type and Cheminert C2 and C4 series valves (standard on Cheminert C1 valves). The continuous contact closure, provided only while the valve is in the inject position, can remote start a chromatograph or data system.
