Autoclave 10VRMM2812 Micro-Metering Valve
Micro-Metering Series
Pressures to 60,000 psi / Temperatures from -100F to +800F
Principle of Operation:
Micro-Metering valves are designed for applications where more precise control of small flow is required than is possible with a standard regulating stem. Barrel and Thimble micrometer design permits settings to be repeated.
Metering is controlled 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 calibrated 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 pressure matching shutoff valve is recommended.
Micro-Metering 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.
- Operating Temperatures vary per model but can range from -100°F to 800°F
- UNS S31600 cold worked type 316 stainless steel body; stem and seat are cold-worked type 316 stainless steel
- Packing below stem threads is PTFE for the 10VRMM, 15PVRMM and 30VRMM valves and nylon-leather for the 60VRMM; see Technical Information section for packing options

- Temperature: standard Parker Autoclave Engineers 10VRMM series valves with PTFE packing may be operated to 450°F
- Repair Kit: R10VRMM2812
Valve Options (add the following suffixes to the valve part number):
- “B“: Cryogenic trim materials and PTFE Glass packing required when below 0°F to -100°F
- “TG“: Standard valve with PTFE Glass packing -100°F to 600°F
- “GY“: Standard valve with graphite braided yarn packing 32°F to 800°F; Parker Autoclave Engineers does not recommend Low Pressure Speedbite sleeve connections below -100°F or above 650°F
- “PM“: panel mount; additional #10-24 screw is included
- “CSS“: N-Dura coated stem and seat
Notes:
- Parker Autoclave Engineers valves are complemented by a complete line of fittings, tubing, check valves and line filters.
- Traceability is ensured by use of heat and purchase order codes etched on valve body that also include model number, MAWP rating, and material type references.
- All valves include connection collar and gland nut unless requested otherwise.
