Needle valves

  • Easy installation
  • Precise metering and leak-free shut-off
  • Internal locking nut to prevent unscrewing stem from body
  • Construction allowing higher pressures
  • Unbreakable handwheel
  • Equipped for panel mounting
  • Cleaned for oxygen service per CGA G-4.1

Pressures in appliances using cryogenics are usually sensitive to higher pressures and the needle valves help regulate the pressure to a desired output. Pressure regulation is manually actuated by using the handwheel that require multiple turns for a small regulation of gas and fluid flow/stop.
