 Needle Valves
We manufacture & export a wide range of Forged / Bar Stock Needle Valves, Forged Body Needle Valves and Brass Needle Valves as per the industry standards & specifications. These needle valves are manufactured utilizing advanced manufacturing methods & pass through stringent quality tests at every stage of production.

Features
  • Pressure rating up to 5000 psi(340 bar) at 380C (1000F).
  • Temperature rating from -530C (-650F) to 2320C (4500F) with standard PTFE packing, up to 3150C (6000F) with Grafoil packing.
  • Materials: Standard 316SS and Brass. (Other materials are available on request as factory specials).
  • Forged body with straight and angle pattern.
  • Panel mounting without packing disruption.
  • Wide choice of end connection: AVLOK™ Tube Fittings, Male & Female NPT or PT (ISO 7/1) thread, Socket Weld ANSI/ASME B16.11.
  • Standard lubrication: Nickel anti-seize lubricant (Hydrocarbon carrier
  • Standard seat: Metal to metal/body material.
  • Optional sea: Metal to metal/satellite, hard coating, soft seat.

Choice of Stem
Vee Steam is standard for pressure tightness even at elevated temperatures. Regulating Stem & Soft-seat Stem are optional.

Sour Gas Service
Materials for wetted valve component are selected in accordance with NACE standard MR 0175-2000 for sulfide stress cracking resistant.

Testing
  • Standard Factory Test: Every needle valve is 100% factory tested with air and nitrogen at 1000psi (69bar) for leakage a the seat and packing. Each test is performed to maximum allowable leak rate of 0.1sec/min.
  • Optional Hydrostatic Test: This hydrostatic shell test is performed with pure water at 1-1/2 times of the working pressure. Other optional tests are available upon request.

Safe Valve Selection
When selecting the needle valves, the total system design must be considered to ensure safe, trouble-free performance. Valve function, materials compatibility, adequate ratings, proper installation, operation and maintenance are the responsibility of the system designer or user.
