The orifice size is 0.13” with a Cv of 0.207 for inline and Cv of 0.299 for the angle pattern valve. They provide accurate and stable control of flow rates in various instrumentation applications. These metering valves are designed to have the vale stem threads not in contact with the process media. This unique feature increases the valve's stem life cycle and prevents the valve from “seizing up” with various media(solvents, etc.).

各种终端连接尺寸和密封材料提供了不少多功能应用。这些紧凑型计量阀在不同密封温度范围内可工作到1000 psi（69bar）。 A wide variety of end connection sizes, and seal materials provide considerable application versatility. These compact, metering valves work up to 1,000 PSI (69 BAR) at all seal temperature ranges.

此外，这些阀可有角型结构和直线式阀体模式，以协助安装在复杂的合适的管路系统上。安装人员应注意，这些计量阀不可以用作切断阀。 如果系统有关闭要求，派克V系列针阀可以与这些计量阀一起使用。 In addition, these valves are available in angle and inline body patterns to assist installation in complex tubing systems. The installer should note that these metering valves are not intended for use as a shut-off valve. A Parker V Series needle valve can be utilized in conjunction with these metering valves if the system has a shut off requirement.
