Item # 60VRMM4882, VRMM Series MicroMetering Needle Valves




MicroMetering valves are designed for applications where more precise control of small flows is required than is possible with a standard regulating stem. Barrel and Thimble micrometer design permits settings to be repeated. Metering is effected by a finely tapered stem acting in a precisely mated replaceable seat. Very fine stem position is achieved utilizing a 40 TPI thread. The Barrel and Thimble are set for proper metering at the factory. These valves are designed for metering only and cannot be used as a shutoff valve. Minimum flow is factory set and occurs at “0” position. DO NOT OPERATE THE VALVE BELOW THE ZERO POSITION OR DAMAGE WILL RESULT. When shutoff action is required, a correlated shutoff valve from AE series 10V, 30VM or 60VM should be installed in series with the MicroMetering valve.

MicroMetering Valve Features:
  • Barrel and Thimble design permits repeatable settings.
  • Barrel divisions every 0.025”.
  • 25 Thimble divisions, each representing 0.001” stem travel.
  • One revolution = 0.025” stem travel.
  • Cold-worked type 316 stainless steel body with stainless steel packing gland. Stem and are cold-worked type 316 stainless steel.
  • Packing below stem threads is Teflon for the 10VRMM and 30VRMM valves and nylon- leather for the 60VRMM. For packing options, see Technical Information Section.
  • SpeedBite “W” connections are used on the 10VRMM and AE High Pressure coned-and threaded connections on 30VRMM and 60VRMM.
Autoclave valves are complemented by a complete line of fittings, tubing, check valves and line filters.
