Parker FM-4 系列PFA/PTFE 流量计用于需要精密液体流量控制的超高纯应用。它提供耐腐蚀性，采用无泄漏操作的卡套技术 (压力120 psig)。Parker派克FM-4系列是3/4"PFA/PTFE流量计， 非常适合需要对流体进行精确控制和测量的高纯应用。采用PTFE体、高纯PFA桶、精密加工针阀元件。这些特点使流量计具有高循环寿命、优秀的泄露完整性和优异的耐腐蚀性。

并非典型的面对面密封，FM-4系列采用压缩技术将桶与本体进行密封。确保可靠、无泄漏操作，使端口可360°定位，增加灵活性。流量计的PTFE浮动设计允许在各种化学品中的连续读出和能见性。

Parker FM-4系列可配备Parflare入口和出口连接方式，节约装配和安装时间，确保洁净至关重要的应用中无泄漏密封性能。

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.
