Proportional Directional Control Valves Size 6

Transcription

1 Proportional Directional Control Valves Size 6 Direct controlled, electrically adjustable Interface to DIN 2 30 and ISO 0 PN [p max. ] = 35 bar Description (standard units) Design The proportional directional control valve size 6 is based on the 5chamber system, and is in the form of a slide valve. Application The proportional directional control valve can be used to control the direction and speed of hydraulic cylinders and hydraulic motors and is employed in cases wherer a servo valve would be too expensive and a normal directional control valve would not offer a sufficient range of functions. The electrical control allows the wide variety of motions to be executed simply and extremely precisely by means of the continouslycontrollable signal. Using the pressure balance as intermediate component, the proportional directional control valve can taken over a flow control function. Mounting The units are screwed to subplates and sealed by means of Orings. Line connection Subplate, interface to DIN 2 30A 6 and ISO 0AB03A. Features Speed and direction control in accordance with setpoint specification Program control, remote control Springcentred robust design Inexpensive system solution With pressure balance, loadcompensated speed control.

4 Ordering The units are designated by their type number. The composition of this number can be drawn from the type code. The standard versions are listed in the type survey. When ordering any of the standard versions, please state type number as well as catalog number to preclude possible misinterpretations. When inquiring about or ordering units not listed in our type survey of this publication, the type number made up by you by means of the type code, however, will do. The corresponding catalog number will then be stated in our confirmation of order. Orings are enclosed with flanged units. balance, subplate, drive electronics and mounting screws must be ordered separately. Example of order Proportional directional control valve, size 6, for flange mounting, Symbol 87, with Code 205, pressure balance, mating subplate G / and drive electronics.
