IST Right K Valve

  • Material: Chrome plated brass
  • Valve knob material: Thermal plastic
  • Available in 200 or 300 bar version
  • Tank neck valve thread: 3/4" – 14NSP or M25 x 2
  • DIN female thread: G5/8 or M25
  • Burst disk rupture pressure @ 372 BAR (5400psi)

DOLPHIN TECH designate right and left K valves by the hand that can operate their shock absorbing, low friction knobs when diving. This means the "right" valve is the one reachable by the outstretching right hand and vise versa for the left. The right valve can also be easily identified by its plug’s / stop nut’s indentation marks while the left valve has none. Both valves are completely modular and versatile. Depending on the dive requirement, they can be used independently, with H valves, or linked together via a cross bar. Each of these attachments has double O-rings for a more secure sealing.

* The 200 bar version comes with YK-04 DIN to yoke tank valve converter

I am about to purchase item ISTVLVRT--G5MT3I. I need a M25x2 thread config. what is the difference in 200 or 300 Bar in this particular item? I understand the pressure ratings but are there any mechanical differences?

Hey There, the 200 versus the 300 bar is that the 200 is shallower or less depth and less threads than the 300.
