6-Port Medium Pressure Selection Valves Instruction Guide - Bulkhead Version

by IDEX Health & Science

What is the Medium Pressure Selection Valve?

The Medium Pressure Selection Valve is a 6-Way selection valve appropriate for applications up to 1,000 psi (69 bar). The central port is connected to one of the six periphery ports. The valve can be rotated 60 degrees to select the appropriate inlet or outlet port.

Bulkhead Mounting Instructions

  1. Drill the appropriately sized hole in the bulkhead (see Diagram A).
  2. Remove the rotary knob from the valve with the included Allen wrench; remove the Mounting Nut and Washer and set them aside.
  3. Insert the shaft of the new Valve through the bulkhead, aligning the Notch in the bulkhead’s mounting hole with the “Key” on the Valve body (see the Valve pictured in Diagram C). Place the Nut and Washer (removed in Step 2) on the shaft side and tighten, followed by reattaching the Rotary Knob (see Diagram B).
