2) Standard version X=00 type

3) Only external seals for 10 valves

Description

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.
