Ham-Let H-300U Series Needle Valves

 

Ham-let’s H-300U series needle valves feature stainless steel and brass construction in both straight and angled patterns and a variety of stem types ranging in sizes from 3mm to 12mm. The included packing bolt allows for easy panel mounting, so no packing disassembly is required. The chevron stem packing provides low operating torques, and Belleville washers are used to compensate packing wear. They also use a special synthetic, anti-seize stem lubricant for best resistance to hot media.

A variety of stem options are available:

  • 8A Regulating, which is used where some degree of flow control is required.
  • 8B V-Stem, which is the standard stem tip used for the on/off operation in general purpose liquids and gas service.
  • 8C Non-rotating stem, which is typically used in high cycle applications to extend valve life and prevent stem rotation inside the body tip. This type is suitable for gaseous high-pressure applications.
  • And 8D Soft Seat, which requires a lower seating torque than a metal stem tip. It is a great choice for clean gaseous high-pressure applications.
