VLSC-10A-8-TF

RE18321-71-01(2023-11-07)
Description

When pressure at 1 rises above the selected spring bias pressure against the spool, the valve shifts to allow block from 2 to 1. Pilot pressure at 3 is additive to the spring bias pressure. The valve may be used in switching or compensation type applications, and will maintain a constant pressure drop across a fixed (or variable) orifice downstream of 1 when installed and piloted per the diagram above.

VLSC-10A-8-TF is provided of a damped type spool, especially designed for demanding applications.
