Catalogue Information Mobile Directional Control Valve Parker is the world's leading supplier of motion control components and system solutions serving the mobile, industrial Parker is your single source for any hydraulic valve requirement. We provide a wide selection of open-centre and load-sense directional control valves for construction, off-highway, or on-highway applications. Many of our open-centre valves can be adapted and used as constant-pressure unloaded valves. Each of these technologies offers unique features for improved machine perform- ance over traditional, open-centre...

General Information Mobile Directional Control Valve intended for machines such as small and midsize wheel loaders, mine loaders, fork-lift trucks, etc. It is designed for use in closed-centre (LS) hydraulic systems with variable pumps, and is suitable for tough operating conditions. Simple installation Good machine design and the right hydraulic system gives a cost-effective installation, which in turn gives a competi- tive product. The pump and work ports in that hosing and piping can be kept to an absolute minimum. The valve is equipped with double work ports at 180°, which eliminates...

Technical Information Mobile Directional Control Valve Also see table on page 7. U6 Connections with UNF threads, U3 Connections with UNF threads, Counter pressure function [io] The valve can be equipped with a counter pressure valve in the tank connection to ensure that oil from the cylinders is used primarily to replenish the system. This is possible thanks to the generous gallery dimensions and anti-cavitation valves. The valve MX No counter pressure valve in tank gallery. MF4 Counter pressure valve set to 4 bar at 20 l/min.

Spool Section Mobile Directional Control Valve The spool is the most important link between the actions of the machine operator and the movement of the controlled function. Parker therefore goes to great lengths to optimize spools for different flows, load conditions and functions. This ongoing devel- opment work results in the continual introduction of new spools. For this reason, it is not practical to list in this catalogue the different spools available at any one time. For assistance in the choice of spool, we therefore ask you to contact Parker directly. Parker spools are divided into...
