Brass Cylinder Hi/Lo Valves

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;
  common safety device and hand wheels are widely available.
