Flow control valves type QV-06 pressure compensated, two way, size 06 not ISO
QV are flow control valves with pressure compensator 햲: the controlled flow rate is
independent of pressure variations.
They are usually supplied with a built-in check valve 햳 to allow the free flow in the
opposite direction.
The flow is regulated by turning a graduate micrometer knob 햴. Clockwise rotation
increases the flow regulation.
Optional versions with locking key 햵 on the adjustment knob are available on
request.
Valves designed to operate in hydraulic systems with hydraulic mineral oil or
synthetic fluid having similar lubricating characteristics.
