开关放气阀 GF-00050-00
In prime/purge valves, mobile phase flows around the needle when the valve is closed, relieving the back pressure from the column. When the valve opens, mobile phase vents to waste to prime the pump. The on/off function i…

Simplify your liquid or gas handling application with a VICI Precision Sampling Micro valve. The unique design of the fitting detail allows a leak-free seal with no potential for rotor damage from overtightening.
SD valves select one of 4 to 16 dead-ended streams. The selected stream flows from the outlet to a sample valve, pressure sensor, detector, column, etc. The same flowpath can also be used to direct one stream to a number …
Valco internal sample injectors are designed for injecting samples that are too small for conventional loop injection, achieving sample sizes of .06 µl to 2 µl. The internal sample "loop" is actually an engrav…
SC valves select one of 4 to 16 dead-ended streams. The selected stream flows from the outlet to a sample valve, pressure sensor, detector, column, etc. SC valves are similar to the SD configuration in that regard, but in…
SF valves are similar to SDs and SCs, selecting a stream and sending it to the outlet. However, SFs allow the non-selected streams to flow through individual outlets instead of a common outlet. See application suggestion
ST valves are used for multi-column, multi-sample, or multi-trap operations, and are available for use with 4 to 16 loops, or positions. See application suggestion.
ST valves are used for multi-column, multi-sample, or multi-trap operations, and are available for use with 4 to 16 loops, or positions. See application suggestion.
The STF valve is a variation of the ST flowpath, with the single difference that the non-selected streams are returned to their own vents or sources rather than being dead-ended or trapped, as they are in the standard ST …
Standard valve body material is Nitronic 60 stainless steel. Other materials are available: Hastelloy C, Inconel 600, Monel 400, Nickel 200, Nitronic 50, titanium, and zirconium.
