Description

VHD Series Double O-Ring High Pressure Valves for Service Pressures of 3500-4500PSI

NGT and 25E Tapered Threads

KEY FEATURES:

  • Fill the high-pressure port (347, 680, or 701) to
    4500PSI; gas is delivered through the 3000PSI outlet
    (346, 580, or 540) at 700-1000PSI.
  • Regulator is cycle-tested to exceed typical cylinder life,
    ensuring long-term durability.
  • Dual outlets support both lower and higher pressures from
    the same cylinder.
  • Copper beryllium spring ensures compatibility with
    oxygen and breathing air mixtures.
  • 3000PSI outlet protected by a secondary 2800-3000PSI safety device.
  • Robust forged components and double O-ring seals provide superior
    strength and leak protection in ultra-high-pressure applications.
  • No special adapters needed for filling; easy operation at all pressure levels.
  • 100% leak tested, meeting and exceeding CGA V9 and ISO 10297
    standards including stringent adiabatic oxygen compressing testing.
  • Valves are bagged for cleanliness in all gas services.
  • Unitized plug with hex and threads for easy installation;
