Parker Autoclave VRMM Series micro-metering valves

Parker Autoclave 的 VRMM 系列微量計量針閥用于精確計量高達 60,000 psi (4137 bar) 的流體。這些棒料閥設計有細錐形閥桿，可在精確配合的可更換閥座中關閉。派克 Autoclave 的 VRMM 系列微量計量閥設計用于需要比標準調節閥桿更精確控制小流量的應用。筒體和頂針千分尺設計允許重復設置。計量是通過作用在精確配合的可更換閥座中的細錐形閥桿實現的。使用 40 TPI 螺紋可實現非常精細的閥桿位置。桶和頂針在出廠時已設置為正確計量。

這些閥門僅設計用于計量，不能用作截止閥。最小流量為出廠設置，出現在“0”位置。請勿在零位以下操作閥門，否則會造成損壞。當需要關斷動作時，派克AE系列10V、30VM或60VM的相關關斷閥應與微量計量閥串聯安裝。

除了它們的許多功能外，這些微量計量閥在各種應用中提供可靠和無故障的服務。

Parker Autoclave's VRMM Series micro-metering valves are used for the precise metering of fluids up to 60,000 psi (4137 bar). These bar stock valves are designed with a finely tapered stem that closes in a precisely mated replaceable seat.

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.

Markets:
- Oil and Gas
- Petrochemical
- Chemical
- Research


Features/Benefits:
- 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.



Applications:
- High Pressure Pilot Plants
- Research Panels
- High Pressure Fluid Handling Systems
