Milli-Mite® 1300 Series
Forged Metering Valves
Typical Applications
• Fine metering in medical and biochemical gas or vapor analysis
• Sampling and analyzing water and air pollution
• Chromatographs, mass spectrometers and other instruments where fine metering is required
Features & Benefits
• Metering accuracy - 18 turn displacement of stem provides unparalleled performance and repeatability
• 1° and 3° stems provide a wide flow range with ultra fine metering control
• Panel mounting is standard for all valves
• Precision orifi ce and close thread tolerances minimize hysteresis
• Micrometer vernier handle provides visual control and repeatable stem settings
• Dyna-Pak ® wafer packing below the stem threads provides leak tight service
• Special High Tolerance NPT Thread
Micromite® 1600 Series
Forged Metering Valves
Typical Applications
• Chromatography
• Mass Spectroscopy
• Sampling and fine metering
• Pollution analyzing instrumentation
Features & Benefits
• 18 turn non-rotating stem
• Low internal volume provides low flow control
• Non-rotating stem minimizes unwanted variability of flow rate
• Unique thread design allows tapered needle portion of the stem to be withdrawn into the outer stem
• O-ring seals below the stem threads provide smooth operation and eliminate backlash
• Panel mounting is standard for all models
• Dial indicator provides repeatable positioning of stem in full turns and tenths of a turn from closed to fully open.
• Position by fi nger tip rotating the knurled aluminum dial.
• A position lock prevents accidental movement of the handle and resulting errors in flow data.
• The size and design of the handle assembly provide an attractive appearance for equipment panels.
• Special High Tolerance NPT Thread
2300 Series
Bar Stock Metering Valves
Typical Applications
• Metering liquids and gases on analytical equipment
• Laboratory sampling
• Gas chromatography, analyzers
• Flow meters and gauges
Features & Benefits
• Micrometer vernier handle provides visual control and precise establishment of flow settings.
• 20 turn stem displacement for fine metering
• 2 orifi ce sizes 0.062˝ (1.59mm) and 0.125˝ (3.17mm) are available with standard 8° stem
• Spring loaded stem in all 316 stainless steel valves prevents galling and enlargement of the orifice.
• For ultra fine metering, a 1° spring loaded stem design is available for all valves with 0.062˝ (1.59mm) orifi ce. See flow curves for details.
• Panel mounting is standard on all valves
• Bonnet lock prevents accidental disengagement of bonnet.
• Special High Tolerance NPT Thread
