When pressure at ① rises above the selected spring bias pressure against the spool,
the valve shifts to allow flow from ① to ② . Pilot pressure at ③ is additive to the spring
bias pressure. The valve may be used in switching or compensation type applications.
当①口的油压克服弹簧设定压力时，油液从①口到②口流动。③口压力叠加到弹设定
值上。应用在开关或者补偿场合。
