IST Balanced Diaphragm Regulator Valve R4

The new flagship regulator has all the performance and style that a diver needs. The R4 first stage utilised the well proven balanced diaphragm design to satisfy even the most demanding diver. Along with our award winning second stage, this combination is unbeatable.

R-4 First stage features:

  • New balanced diaphragm design with outstanding flow characteristics. The intermediate pressure drop is kept to a minimum even with heavy flow demand.
  • 2 fixed high pressure ports and 4 angled low pressure ports for better hose routing.
  • R-4 is capable of keeping intermediate pressure steady and remains virtually unaffected by depth or remnant tank pressure.
