Description
Flow is allowed from 2 to 3 until the pressure at 1 rises to the selected spring setting. Upon reaching this pressure, the spool shifts upward, blocking flow 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.
VDSB-10A-6 is especially designed for application requiring high value of shifting pressure.
¹) Measured at 200 bar (2900 psi)
