Needle Valves

PANAM Needle Valves are specifically designed and manufactured for use in corrosive and hazardous environments. These valves are used in process control, instrumentation and flow control applications and are precision machined to provide a high quality, low cost alternative.

Hex Bar Needle Valves

PANAM HB Needle Valves are hex bar stock valves and are constructed out of 316 Stainless Steel (SS) or A105 Carbon Steel (CS), however exotic metallurgy is available for special order. Standard end connections include female or male threaded (NPT) however BSP, ISO, DIN, and JIS tapered pipe ends are also available.

Hex-bar needle valve

General product features:

  • Union bonnet or screwed bonnet connection
  • Metal to metal seat
  • Rolled and hard plated stem threads and tip stellated to prevent galling and extend life of valve
  • Two-part stem tip arrangements
  • Non-rotating ball tip to ensure bubble tight seal and shut-off
  • One-piece body assembly
  • Maximum Working Pressure (MWP)
    • 6000 psi (400 bar) at 200°C
    • 10000 psi (700 bar) at 120°C
  • Temperature rating: -54°C to 240°C
  • Built to MSS-SP-99
  • ISO 9000 Certified
  • High temperature model with Grafoil packing available upon request

Quality test procedure:

  • Nitrogen Gas at 1200 psi (80 bar) to ensure no leakage at seal and seat
  • Hydrostatic test with pure water at 1.5 times maximum working pressure (MWP)
  • Optional tests including Helium and Temperature available upon request

Mini Needle Valves

PANAM Mini Series Needle Valves are exclusively ¼”, and are designed for small volume applications. Applications include isolation of smaller instrumentation such as receiver gauges and instrument gas in dehydrator and separator packages. Mini Valves are available in MNPT or FNPT configurations in both A105 Carbon Steel and 316 Stainless Steel NACE and stem packings are made of Viton or PTFE Teflon.

Mini needle valve

General product features:

  • Vee tip design for accurate flow control
  • Rolled and hard plated stem threads and tip stellated to prevent galling and extend life of valve
  • Mirror finished stem is burnished to 16RMS to extend packing life and aid in smooth stem operation
  • Fully supported packing to reduce the need for adjustments
  • Packing nut is fast and easy to move for external adjustments
  • Dust cap prevents contaminant and lubricant washout from bonnet assembly
  • Maximum Working Pressure (MWP) and Temperature
    • 4000 psi (280 bar) at 200°C
  • Temperature rating: -50°C to 121°C
  • Built to MSS-SP-99
  • ISO 9000 Certified

Quality test procedure:

  • Nitrogen Gas at 1200 psi (80 bar) to ensure no leakage at seal and seat
  • Hydrostatic test with pure water at 1.5 times maximum working pressure (MWP)
  • Optional tests including Helium and Temperature available upon request

High-pressure Needle Valves

PANAM High Pressure Series Needle Valves are specifically designed for use in corrosive and hazardous environments. They are built to 10000 psi (700 bar) or 20000 psi (1400 bar) and are composed of high grade, 316 Stainless Steel. Generally, end connections are male or female NPT, however NSP, ISO, DIN, and JIS tapered pipe ends are available upon request.

General product features:

  • Metal to metal seat or stellited seat
  • One-piece body construction with no welding
  • Rolled and hard plated stem threads and tip stellated to prevent galling and extend life of valve
  • Two-part stem tip arrangements
  • Non-rotating ball tip to ensure bubble tight seal and shut-off
  • Maximum Working Pressure (MWP)
    • 10000 psi (700 bar) at 200°C
    • 20000 psi (1400 bar) at 120°C
  • Temperature rating: -50°C to 93°C
  • Built to MSS-SP-99
  • ISO 9000 Certified

Quality test procedure:

  • Nitrogen Gas at 1200 psi (80 bar) to ensure no leakage at seal and seat
  • Hydrostatic test with pure water at 1.5 times maximum working pressure (MWP)
  • Optional tests including Helium and Temperature available upon request

Hex Bar Block and Bleed Valves

PANAM HB Block and Bleed are similar to HB Needle Valves, except they have a vent port on the base of the valve to release excess fluids once the flow of fluid has been blocked, to prevent it from going downstream.

They are constructed out of 316 Stainless Steel (SS) or A105 Carbon Steel (CS), however exotic metallurgy is available for special order. Standard end connections include female or male threaded (NPT) however BSP, ISO, DIN, and JIS tapered pipe ends are also available.
