Description

Flow is blocked from 2 to 3 until the pressure at 1 rises to

the selected spring setting. Upon reaching this pressure, the

spool shifts upward, allowing flow from 2 to 3 until pressure

at 1 drops below the set point. The spring chamber is drained

to 3, thus any pressure at 3 is additive to the spring setting.

VDSA-10A-6 is especially designed for application requiring

high valve of shifting pressure.
