针阀 Needle Valves

派克所有黄铜针阀都是金属密封，用于流量需要精确控制的应用场合。 Parker's all brass needle valves have a metal-to-metal seats and are for use in applications in which the desired flow must be maintained with little to no variance.

针阀通过阀芯机构来进行液体或者气体的流量控制。使用针阀，将流量调节到某个特别需求的流量大小就有了可能性。因此针阀对于需要精确流量的应用很有效。派克黄铜针阀都是金属-金属座环，通过细牙螺纹来进行调节，因此是流量需要精确控制应用的理想选择。派克针阀的可以选择低温密封材料，低温性能可以达到-40F。 Needle valves create a means of controlling the flow of liquids or gases through the valve mechanism. It is possible to easily adjust the flow rate to any specific amount desired, making the needle valve useful in a number of applications. Parker's all brass needle valves have metal-to-metal seats with fine thread screwdown making them ideal for situations in which the desired flow must be maintained with little to no variance. By controlling the needle valve rate, stress on the delivery system is kept to a minimum. The specialty formulated low temperature seal in the Parker needle valve remains elastic to temperatures as low as -40°F.
安装时特别注意，需要与座环方向相反。 Parker's needle valves should always be installed with the pressure against the seat.
