4 Port 2 Pos internal Volume Valve, universal electric Actuator, RS232/485, 1/16'' Fitting, 0.4 mm Port, 50°C / 250psi, for Liquid, 0.2µl, PPS/E2

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.

Cheminert Nanovolume™ injectors and switching valves are ideal for high speed, high throughput techniques which demand a valve and fitting system that minimize internal volume and eliminate dead volume.
