Parker FM-4 系列PFA/PTFE 流量計用于需要精密液體流量控制的超高純應用。它提供耐腐蝕性，采用無泄漏操作的卡套技術 (壓力120 psig)。Parker派克FM-4系列是3/4"PFA/PTFE流量計， 非常適合需要對流體進行精確控制和測量的高純應用。采用PTFE體、高純PFA桶、精密加工針閥元件。這些特點使流量計具有高循環壽命、優秀的泄露完整性和優異的耐腐蝕性。

并非典型的面對面密封，FM-4系列采用壓縮技術將桶與本體進行密封。確保可靠、無泄漏操作，使端口可360°定位，增加靈活性。流量計獨特的PTFE浮動設計允許在各種化學品中的連續讀出和能見性。

Parker FM-4系列可配備Parflare入口和出口連接方式，節約裝配和安裝時間，確保潔凈至關重要的應用中無泄漏密封性能。

The is designed for ultra-high purity applications where precise flow control of liquids is required. It offers extreme corrosion resistance and uses compression technology for leak-free operation (up to 120 psig).The Parker FM-4 Series is a 3/4 inch PFA/PTFE Flowmeter that’s ideally suited for high purity applications where precise control and measurement of liquids is required. It utilizes a PTFE body, a high-purity PFA barrel, and precision-machined needle valve components. These features afford the flowmeter high cycle life, excellent leak integrity, and exceptional resistance to aggressive liquids.

Rather than a typical face-to-face seal, the FM-4 Series utilizes compression technology to seal the barrel to the body. This ensures reliable, leak-free operation and enables 360-degree port orientation for increased flexibility. The flowmeter’s unique PTFE float design allows for consistent read out and visibility in a wide range of chemicals.

The FM-4 Series is fitted with Parflare inlet and outlet connection types, which reduce assembly and installation time, while ensuring a leak-tight seal for performance in applications where cleanliness is critical.
