The proportional directional spool valve type EDL from HAWE Hydraulik SE is well suited for hydraulic positioning and actuating functions in agricultural machines.
- Controls direction and speed of movement of several hydraulic consumers in parallel and independently of the load
- Implementation of every function remains unaffected by implementation of the other functions
- Operates with load-sensing system, and is controlled directly and actuated electrically
- Flow rates for each different consumer can be adjusted individually
- Values ranging from less than one to 50 l/min are possible
- Spool pistons are available in seven graduated sizes, with the smallest spool size allowing a maximum flow rate of 3 l/min
- Provides optimal resolution and enables speeds of hydraulic motors to be controlled with very high precision
- For system pressures of up to 320 bar
- Flow resistance is 50% lower than usual, improving energy efficiency of hydraulic system
- Flange hole pattern is same as for size 2 of the series PSL proportional directional spool valves for a volume flow up to 60 l/min
- Can be provided with additional hydraulic functions by means of flange-mounted blocks and intermediate plates from the modular system
- Type EDL and PSL valves can be combined very easily in a joint control block if specific consumers need to be controlled via CANbus
