VRMM系列微计量针型阀 Needle Valve,MicroMetering - VRMM Series 60,000PSI

派克 Autoclave的VRMM系列微计量阀用于精确计量高达60,000 psi（4137 bar）的流体。这些棒状阀设计有细锥形的阀杆，该阀杆在精确配合的可更换阀座中关闭。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.

派克 Autoclave的VRMM系列微计量阀设计用于要求比标准调节杆更精确地控制小流量的应用。套筒和顶针千分尺设计允许重复进行设置。计量通过作用在精确配合的可更换阀座中的细锥形杆来实现。利用40 TPI螺纹可实现非常精细的阀杆位置。枪管和顶针已在工厂设置为正确计量。 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.

这些阀仅用于计量，不能用作截止阀。小流量是出厂设置的，发生在“ 0”位置。请勿在零位以下操作阀门，否则会导致损坏。当需要关闭动作时，应将与Parker AE系列10V，30VM或60VM相关的关闭阀与微量计量阀串联安装。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.

这些微计量阀具有众多功能，可在各种应用中提供可靠且无故障的服务。Along with their many features these micro-metering valves provide dependable and trouble free service in wide variety of applications.
