    Parker 針閥
    Parker Needle Valves
    VRMM系列微計量針型閥 Needle Valve,MicroMetering - VRMM Series 60,000PSI

    派克 Autoclave的VRMM系列微計量閥用于精確計量高達60,000 psi(4137 bar)的流體。這些棒狀閥設計有細錐形的閥桿,該閥桿在精確配合的可更換閥座中關閉。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系列微計量閥設計用于要求比標準調節桿更精確地控制小流量的應用。套筒和頂針千分尺設計允許重復進行設置。計量通過作用在精確配合的可更換閥座中的細錐形桿來實現。利用40 TPI螺紋可實現非常精細的閥桿位置。槍管和頂針已在工廠設置為正確計量。 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.

    這些閥僅用于計量,不能用作截止閥。小流量是出廠設置的,發生在“ 0”位置。請勿在零位以下操作閥門,否則會導致損壞。當需要關閉動作時,應將與Parker AE系列10V,30VM或60VM相關的關閉閥與微量計量閥串聯安裝。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.

    這些微計量閥具有眾多功能,可在各種應用中提供可靠且無故障的服務。Along with their many features these micro-metering valves provide dependable and trouble free service in wide variety of applications.
