Cartridge Valves - Directional Control Valves - 4-ways

VDSP-20B

RE18320-89-01(2023-11-07)
Description

In neutral position, all ports A, B, P, and T are blocked. When remote pilot signal at port X1 rises to overcome the spring bias against the spool, the valve shifts to allow flow between P and A, and between T and B. When remote pilot signal at port X2 rises to overcome the spring bias against the spool, the valve shifts to allow flow between P and B, and between A and T.

1) Measured at 300 bar (4500 psi) from A-B to P-T-X1-X2

2) Only external seals for 10 valves
