  • BASIC HYDRAULIC THEORY HYDRAULICSUPERSTORE

    The relief valve limits the system pressure to a preset amount. A hydraulic system using a double acting cylinder and a 4way valve differs from the single acting cylinder system in that the cylinder can exert force in both directions. With the control valve in neutral, flow is returned to the reservoir.

  • Principles of Hydraulic Pressure

    Figure 105.Pressure to a fluid transmits in all directions. PRINCIPLES OF HYDRAULIC PRESSURE A Frenchman named Pascal discovered that a pressure applied to any part of a confined fluid transmits to every other part with no loss. The pressure acts with equal force on all equal areas of the confining walls and perpendicular to the walls.

  • Valves

    Valves are used to manipulate the flow of hydraulic fluid within a hydraulic circuit and are activated either mechanically or electronically. Directional Control Valves are the most commonly used valve in a hydraulic system. Control valves direct the flow of hydraulic fluid from the pump to the actuators or other sections of the hydraulic circuit.
