流量控制阀， 压力补偿型
A cartridge-style adjustable
pressure-compensated flow
control valve
压力补偿可调型，插装式流量阀
SYMBOL
压力 – 流量曲线 PRESSURE DROP VS.FLOW
说明 DESCRIPTION
The valve maintains a constant flow within specified accuracies from ① to ② regardless
of downstream load pressure. When flow produces a minimum predetermined
pressure differential across the compensator spool control orifice, the spool shifts
against the spring force to throttle the flow and maintain the flow setting. Reverse flow
is not regulated.
不管负载压力如何变化，从①到②口的流量都能保持在一定的范围内。当油通过固定
节流孔时，引起极小的压力差， 阀芯开始响应负载变化，通过压力补偿，可维持精确
的流量。油液从②到①反方向流动，没有压力补偿。
