Modular fast/slow valves type DHQ and DKQ

compensated flow control and by-pass solenoid valve, ISO 4401 sizes 06 and 10

Table D170-6/E

DHQ and DKQ are modular units compo-

sed by one by-pass solenoid valve  and

one 2-way pressure compensated flow

control valve  type QV-06 (tab. C210).

The flow control valve is provided with a

built-in check valve  to allow the free

flow in the opposite direction.

The flow adjustment is obtained by tur-

ning the graduated micrometer knob .

Clockwise rotation decreases the throt-

tling (passage reduced).

Optional versions with locking key on

the adjustment knob are available on

request.

DHQ = ISO 4401 size 06 interface; con-

trolled flow up to 1,5-6-11-16-24

l/min (depending on models);

free flow up to 36 l/min.

DKQ = ISO 4401 size 10 interface; con-

trolled flow up to 1,5-6-11-16-24

l/min (depending on models);

free flow up to 120 l/min.

Pressure up to 250 bar.

Valves designed to operate in hydraulic

systems with hydraulic mineral oil or

synthetic fluid having similar lubricating

characteristics.
