Needle Valve, Diverter 20DV Series - 20,000 psi

Brand: Autoclave Engineers - by Parker

Parker Autoclave's 20DV Series diverter needle valves are designed with a non-rotating rising stem valve, with working pressures to 20,000 psi (1,379 bar). This diverter valve uses the Parker Autoclave tubing in sizes ranging from 9/16" to 1". 

Diverter valves provide the ability to direct incoming flow to one of two outlets. Flow is changed by rotating the handle in or out causing a double-ended stem to block the flow path to the outlet not needed.

Diverter valves eliminate the need for multiple valves and the possibility of error in flow direction changes. The 20DV series uses Parker Autoclave Engineers' medium pressure connection. 

This coned and threaded connection provides a reliable bubble-tight seal for dependable performance in a variety of applications.
Features
  • Diverts incoming flow to one of two outlet lines
  • Tubing sizes from 9/16” to 1”
  • Rising stem/barstock body design
  • Non-rotating stem prevents stem/seat galling
  • Metal-to-metal seating achieves bubble-tight shut-off, longer stem/seat life in abrasive flow, greater durability for repeated on/off cycles and excellent corrosion resistance
  • PTFE encapsulated packing provides dependable stem and body sealing
  • Stem sleeve and packing gland materials have been selected to achieve extended thread cycle life and reduced handle torque
