With three versions to choose from, Upchurch Scientific® Switching Valves offer several flow distribution options. Each valve has a low swept volume, can withstand pressures to 500 psi (34 bar) and is chemically inert and biocompatible. The PEEK™ and PTFE resin construction results in a valve as durable as it is economical. Each V-100 Series Switching Valve has 0.040" thru-holes and is supplied with Flangeless Fittings for use with 1/16" OD tubing. To use these valves with 1/8" OD tubing, simply replace the supplied fittings with 1/4-28 Flangeless Fittings(You may notice a slight back pressure at higher flow rates, due to the 0.040" thru-holes in these valves).
To operate, all ports must be either connected to a line of your system or plugged. Built-in positioning detents allow these valves to snap into place, ensuring the thru-hole is properly aligned.
Standard manual valves (V-100D, V-100L and V100T) measure 1.80" (45.7 mm) in length. Bulkhead versions (V-101D, V-101L and V-101T) are 2.18" (55.4 mm) long.
Each of the Upchurch Scientific 4-Port Switching Valves is available in standard manual and bulkhead mountable manual configurations. Bulkhead mounting specifications are included and are also available. The bulkhead mountable manual configuration can also be mounted on our M-615-1 Valve Bracket. DC gear motor actuated versions are also available. The bulkhead mountable manual configuration can also be mounted on our M-615-1 Valve Bracket. DC gear motor actuated versions are also available.
Please contact Upchurch Scientific for custom configurations for instrument manufacturers. High pressure switching valve options are available.
Protect sensitive system components (such as a column) during a cleaning cycle with our Diagonal Flow Switching Valve ("D"). This valve eliminates the need to remove, plug and reconnect a low pressure column.
A typical application for a Right Angle Flow Switching Valve ("L") is column switching, allowing two columns to use one detector. Detector switching is another common application for this valve. Plug off the extra port with the included plug.
Your detector switching application may require the flexibility of routing the column effluent to both detectors simultaneously while retaining the ability to isolate each detector. Use our 3-Way Flow Switching Valve ("T"), plugging off the fourth port with the included plug.
