Prop. Directional Spool Valves

Proportional directional spool valve type EDL
Proportional directional spool valves are a type of directional valve. They control the direction of movement and the velocity of individual or multiple hydraulic consumers actuated simultaneously. Control is independent of the load and continuous. The directional spool valve type EDL with series connection is actuated directly. The flow rates for the individual consumers can be individually adjusted. The proportional directional
spool valve can be flexibly adapted to different control tasks by means of additional functions in the intermediate plates and ancillary blocks. The directional spool valve type EDL can be combined directly with the proportional directional spool valve type PSL and PSV in size 2 and is therefore suitable for constant and variable pump systems. It is used in mobile hydraulics, in particular in civil engineering and agricultural engineering.

Lifting modules type HMPL & HMPV
The new lifting module type HMPL transforms hydraulic
systems for forklifts with a rated bearing capacity of up to ten tons into flexible, energy-saving, compact solutions. The lifting module is designed as a connection block for the proven proportional directional spool valve type PSL. The forklift arm is raised and lowered using a proportional directional seated valve in the lifting module. This valve allows loads to be moved with outstanding precision at volume flows of up to 160 lpm. Because it is leak-free in closed position, it maintains pressure reliably and thus holds the load securely. The direct fitting of the proportional directional spool valve onto the lifting module allows further functions to be controlled, such as the mast’s tilting function or the sideways movement of the fork and bale clamp.

Prop. directional spool valves type PSL & PSV
Proportional directional spool valves are a type of directional valve. They control the direction of movement and the velocity of individual or multiple hydraulic consumers actuated simultaneously. Control is independent of the load and continuous. The proportional directional spool valve type PSL is suitable for constant pump systems and type PSV for variable pump systems with a pressure/flow controller. The volumetric flows and load pressures for the individual consumers can be individually adjusted. The proportional directional spool valve type PSL and PSV can be adapted to various control tasks, e.g. for safety functions. All sizes can be combined with each other. The proportional directional spool valve type PSL and PSV is used in mobile hydraulics, in particular in crane and lifting equipment, construction and mining machinery, drilling
equipment as well as in offshore and marine technology.
