Parker 调节阀 - Parker Metering Valves
Metering valve, 1000 PSI - NM Series

Parker NM 系列计量阀在高达 1,000 PSI (138 BAR) 的各种应用中提供准确和稳定的流量控制。这些介质流量计量阀的 Cv 为 0.055（内联）和 0.057（角阀体型式）。Parker 的 NM 系列计量阀是具有中等流量的精密阀。孔口尺寸为 0.06 英寸，直列式阀的 Cv 为 0.055，角型阀的 Cv 为 0.057。它们在各种仪器应用中提供准确和稳定的流量控制。这些计量阀的设计使阀杆螺纹不与过程介质接触。这种独特的功能增加了阀门的阀杆生命周期，并防止阀门被各种介质（溶剂等）“卡住”。 各种端部连接尺寸和密封材料提供了相当多的应用多功能性。这些紧凑的计量阀在所有密封温度范围内的工作压力高达 1,000 PSI (69 BAR)。

此外，这些阀门有角度和内联阀体样式，以帮助安装在复杂的管道系统中。安装人员应注意，这些计量阀不能用作截止阀。如果系统有关闭要求，Parker V 系列针阀可与这些计量阀结合使用。

Parker's NM Series Metering Valves provide accurate and stable control of flow rates in various applications up to 1,000 PSI (138 BAR). These medium flow metering valves have a Cv of .055 for Inline and .057 for Angle body pattern.

Parker's NM Series of metering valves are precision valves with a medium flow rate. The orifice size is 0.06” with a Cv of 0.055 for inline and Cv of 0.057 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 valve 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.).
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.

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.
