Control example: double-acting hydraulic cylinder. Possibility of series connection to the existing system (requires connection of a pressure sleeve). Five-digit joystick (1 - 2 - 0 - 3 - 4), spring-loaded, ie it moves back to the vertical position by itself.
Position 0 neutral (vertical joystick) piston rod of both cylinders is stationary - oil overflows. Position 1 (joystick lever in an inclined position) The piston rod of the first cylinder slides out. Position 2 (joystick lever in diagonal reverse position) The piston rod of the first cylinder retracts.
Position 3 (joystick lever at an angle to the left) The piston rod of the second cylinder slides out. Position 4 (joystick lever at an angle to the right) second piston rod retracts. Pump supply (P): female thread BSP 1/2 (or 3/4 we get different versions). Return to tank (T): female thread BSP 3/4.Output for sections (A, B): Female thread BSP 1/2. Series connection (N): Female thread BSP 3/4. Pressure range Maximum supply pressure: 250 bar. Maximum return pressure: 50 bar. Maximum pressure in sections: 300bar.
Bypass valve (safety) set at the factory to 175 bar. Self-adjusting, full turn 30 bar displacement. Permissible ambient temperature: 40 ° C to + 60 ° C. Permissible oil temperature: 15 ° C to + 80 ° C. Dimensions can be changed slightly.
