Threaded needle valve

Needle valves are control valves with a tapered plunger (needle) for very fine adjustment of liquid or gas flow. They take their name from the slender, pointed needle that restricts the flow, and are preferred in low-flow systems that need high precision.

Advantages

  • Fine flow adjustment: the tapered needle changes the flow area in very small steps
  • Tight shut-off: the needle stops the flow completely when seated
  • High-pressure capable: compact body, pressure ratings up to PN400
  • Stainless steel internals: long life, low maintenance

Applications

  • Instrument and measuring lines (gauge and transmitter connections)
  • Sampling and analysis lines
  • Low-flow gas and liquid dosing
  • Hydraulic and high-pressure test systems
  • Laboratory and test systems
