High-Pressure Needle Valves

MAWP 30,000-60,000 psi

High Pressure Needle Valve Components

SAMI INSTRUMENTS high pressure valves are designed for liquid and gas flow control. Available in a variety of body styles, the valves are suitable for manual operation in temperature ranging from -100°F to 600°F (-73°C to 315°C). SAMI INSTRUMENTS high pressure valves are available in various tubing sizes to satisfy different requirements.

Specifications

  • Pressures Ranging from 30,000 - 60,000 psi ( 2068 to 4139 Bar )
  • Connections from 1/4" to 9/16" coned and threaded tube
  • Non-rotating stem prevents galling and scoring
  • Stem sleeve and packing gland materials have been selected to achieve extended thread cycles and reduced handle torque.
  • Standard materials of construction include 316 L cold-worked stainless steel and glass-filled PTFE.
