Needle Valve, MicroMetering - VRMM Series 60,000 psi

Brand: Autoclave Engineers - by Parker

Add Product to My Catalog

Parker Autoclave's VRMM Series micro-metering 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 Parker AE series 10V, 30VM or 60VM should be installed in series with the micro-metering valve.

Along with their many features these micro-metering valves provide dependable and trouble free service in wide variety of applications.

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 seat are cold-worked type 316 stainless steel
Packing below stem threads is PTFE 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 valves and Parker AE High Pressure coned-and-threaded connections on 30VRMM and 60VRMM valves
