Idex Shut-Off Valves

Shut-Off Valves

  • For low and medium pressure applications
  • Biocompatible, all-polymer flow path
  • Available for 1/16” and 1/8” OD tubing
  • Pressure rated to 500 psi (34 bar)

 

Stop a flow stream quickly with Upchurch ScientificR biocompatible Shut-Off Valves. The bodies are manufactured from either PEEK™ or ETFE, and both versions feature a PCTFE rotor, making them highly resistant to chemical attack. The blue colorant used in some valve configurations has proven not to leach out with common HPLC solvents. Connect semi-rigid or rigid tubing, such as PEEK, stainless steel or fluoropolymer, with the 1/4-28 Flangeless Fittings provided. Soft tubing, such as PharMedR or TygonR (see pages 75 – 89), may be connected to these valves using our 1/4-28 barbed adapters. 

 

Application NOTE:

  • Install a Shut-Off Valve between the solvent reservoir and pump. Then, when it is necessary to disconnect the solvent line, a simple twist of the valve lever eliminates the potential of a hazardous spill.

 

Medium Pressure Switching Valve Applications

  • 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 (see below). 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.
