Needle & Regulator Valves

A valve is a device that regulates, directs or controls the flow of a fluid by
opening, closing, or partially obstructing various passageways.

Valves are technically valves fittings, but are usually discussed as a separate category.

VB16

Pressure Rating up to 6,000 psig

Spec.

  • Working Pressure : 6,000psig
  • Compact design
  • Vee Tip / Soft Seat Stainless Steel
  • DK-Lok 1/4 to 1/2 in. OD
  • Pipe thread 1/4 to 3/4 in.

Brief Description

  • Two-piece chevron PFA stem packing design with
    compensating spring packing.
  • Improves sealing integrity.

VR6

VR6 Series Pressure Rating up to 413bar (6,000 psig)

Spec.

  • Working Pressure : 6,000 psig
  • PCTFE Seat Material
  • Stainless Steel
  • Pipe thread Female NPT 1/4 in.

Brief Description

  • The High Pressure Regulator valve is featured by controlling the pressure toward downstream from zero to 1,000 psig (68.9 barg) precisely and keeping the downstream pressure constantly after adjusting, though the upstream pressure may be fluctuated unexpectedly.
  • The diaphragm made of thin plate of stainless steel is positioned between the body and housing to make sure of stable sealing characteristics and keep the control volume.

V46A

Spec.

  • Working Pressure : 10,000 psig
  • Packing adjustment externally
  • Stainless Steel and Carbon Steel
  • DK-Lok 1/4 to 1/2 in. OD
  • Pipe thread 1/4 to 3/4 in.

Brief Description

  • Chevron PTFE packing provides far improved sealing integrity.
  • Packing below the stem threads is to isolate threads from system fluid and lubricant washout.
  • Non-rotating stem tip closure for long-life and leak-tight shut-off.
  • Lock plate ensures the valve fastened to the body.

VEX110

VR6 Series Pressure Rating up to 413bar (6,000 psig)

Spec.

  • Working Pressure : 10,000 psig
  • Unique sealing cup design on packing
  • Stainless Steel
  • Pipe thread 1/4 to 1/2 in.

Brief Description

  • Unique pressure reacting sealing system eliminates the need of packing adjustment.
  • Sealing cup swells up in system pressure for leak-tight operation.
  • Backseat stem design prevents stem blowout.
  • Stem packing below the threads prevents thread lubricant washout and media contamination.
