Parker Autoclave VRMM Series micro-metering valves

Parker Autoclave 的 VRMM 系列微量计量针阀用于精确计量高达 60,000 psi (4137 bar) 的流体。这些棒料阀设计有细锥形阀杆，可在精确配合的可更换阀座中关闭。派克 Autoclave 的 VRMM 系列微量计量阀设计用于需要比标准调节阀杆更精确控制小流量的应用。筒体和顶针千分尺设计允许重复设置。计量是通过作用在精确配合的可更换阀座中的细锥形阀杆实现的。使用 40 TPI 螺纹可实现非常精细的阀杆位置。桶和顶针在出厂时已设置为正确计量。

这些阀门仅设计用于计量，不能用作截止阀。最小流量为出厂设置，出现在“0”位置。请勿在零位以下操作阀门，否则会造成损坏。当需要关断动作时，派克AE系列10V、30VM或60VM的相关关断阀应与微量计量阀串联安装。

除了它们的许多功能外，这些微量计量阀在各种应用中提供可靠和无故障的服务。

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
