Parker Autoclave VRMM Series micro-metering valves

Parker Autoclave 的 VRMM 系列微量計(jì)量針閥用于精確計(jì)量高達(dá) 60,000 psi (4137 bar) 的流體。這些棒料閥設(shè)計(jì)有細(xì)錐形閥桿，可在精確配合的可更換閥座中關(guān)閉。派克 Autoclave 的 VRMM 系列微量計(jì)量閥設(shè)計(jì)用于需要比標(biāo)準(zhǔn)調(diào)節(jié)閥桿更精確控制小流量的應(yīng)用。筒體和頂針千分尺設(shè)計(jì)允許重復(fù)設(shè)置。計(jì)量是通過作用在精確配合的可更換閥座中的細(xì)錐形閥桿實(shí)現(xiàn)的。使用 40 TPI 螺紋可實(shí)現(xiàn)非常精細(xì)的閥桿位置。桶和頂針在出廠時(shí)已設(shè)置為正確計(jì)量。

這些閥門僅設(shè)計(jì)用于計(jì)量，不能用作截止閥。最小流量為出廠設(shè)置，出現(xiàn)在“0”位置。請勿在零位以下操作閥門，否則會造成損壞。當(dāng)需要關(guān)斷動作時(shí)，派克AE系列10V、30VM或60VM的相關(guān)關(guān)斷閥應(yīng)與微量計(jì)量閥串聯(lián)安裝。

除了它們的許多功能外，這些微量計(jì)量閥在各種應(yīng)用中提供可靠和無故障的服務(wù)。

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
