MODEL
DSCL
Direct-acting, low side, 3-position, shuttle valve
SERIES 1 / CAPACITY: 60 L/min. / CAVITY: T-31A
Low-side (hot oil) shuttle cartridges allow hot oil to be diverted from the low pressure side of a closed loop system.
When both work ports (ports 2 and 4) are at equal pressures the valve is spring-centered to an all-ports-blocked
position. When one of the work ports (port 2 or 4) sees a higher pressure the opposite work port is connected to
the common port (port 3).

TECHNICAL FEATURES
NOTE: Low shift values can potentially result in charge pump pressure alone inadvertently shifting the valve. Use care when selecting shift pressure.
Although this valve goes into a 4-port cavity, the nose (port 1) is not used.
This valve does not have a hydraulic stop and therefore has no pilot flow. Some circuits other than hydrostatic transmissions cannot tolerate the added leakage.
Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge
machining variations.
