Characteristics
The pilot operated directional valves 4D02V (NG10),
4D03 (NG16) and 4D06 (NG25) are offered under Deni-
son brand name. The 4D02V is a high flow version with
a maximum flow up to 170 l/min.
4D03 and 4D06 are based on the Parker D41 and D81
main stage with Denison 4D01 pilot valve.

Integral Check Valve / Pilot Oil Options
Integral check valve in the P port
Mounting an integral check valve in the P port is neces-
sary to build up pilot pressure for valves with P to T con-
nection and internal pilot oil supply. The pressure differ-
ence at the integral check valve (see performance curves)
is to be added to all flow curves of the P port of the main
valve. Directional valves with an integral check valve are
available for the series 4D02V, 4D03 and 4D06.
