Control block EDD Modular Directional Valve

2 Control block EDD Modular Directional Valve Bosch Rexroth Oil Control S.p.A. introduces the EDD size 08 directional control valve with up to 80 l/min to the Bankable product line. These allow electrohydraulic control of actuators (motor or cylinders) in open circuit applications. It is an ideal solution for mobile and industrial applications when the required flow rate is over standard D03. Features Modular directional elements Up to 80 l/min (21 GPM) flow for single functions. Same flange interface as the ED series Optional Integrated antishock valve on A & B ports Direct acting solenoid operated directional spool Advantages Cast body design for performance to size and weight optimization Streamlined design for minimized pressure drop Efficient solenoid system to maximize flow capacity and spool shift performance Zinc plated body and pole tubes for superior corrosion resistance EDD - Technical Data Max. pressure: 310 bar (4500 psi), A & B: 380 (5500 psi) Max. flow: 80 l/min (21 GPM) Ports connection: A & B, SAE 10

Modular Directional Valve Control block EDD 7 EDD Cross section Principles of operation, cross section The sandwich plate design directional valve elements D8_5 are compact direct operated solenoid valves which control the start, the stop and the direction of the oil flow. These elements basically consist of a stackable housing (1) with a control spool (2), one or two solenoids (5), and one or two return springs (4). The spring chambers are connected to the tank port. When the coil is energized, the spool (2) travels and oil is pushed to tank from one of the spring chambers. When energized, the force of the solenoid (5) pushes the control spool (2) from its neutral-central position to the required position, and the required flow from P to A (with B to T), or P to B (with A to T) is achieved. Once the solenoid is de-energized, the return spring (4) pushes the spool thrust washer (3) back against the housing and the spool returns in its neutral-central position. Each coil is fastened to the solenoid tube by a ring nut (6). A pin (7) allows to push the spool (2) in emergency conditions, when the solenoid cannot be energized, like in case of voltage shortage. The secondary cartridge valves are designed for quick response and stable pressure control (8); they also incorporate a reverse flow check for anti-cavitation.
