Cylinder Applies hydraulic force. Cylinder Base Plate For applications such as lifting where additional cylinder stability is required.  Pump Provides hydraulic flow. Hose Transports hydraulic fluid.  Male Coupler For quick connection of the hose to system components.  Female Coupler For quick connection of the hose end to the system components.  Gauge To monitor pressure of the hydraulic circuit.  Gauge adaptor For quick and easy gauge installation.  Swivel connector Allows proper allignment of valves and/or gauges. Used when units being connected cannot be rotated.  Auto-Damper Valve V-10 Used to protect gauge from damage due to sudden pressure variances in the system. Needs no adjustment and allows correct positioning of gauge prior to tightening. Only required in place of Swivel Connector (9) in applications where rapid decompression is likely, such as hole punching.  4-Way Directional Control Valve Controls the direction of hydraulic fluid in a double-acting system.  3-Way Directional Control Valve Controls the direction of hydraulic fluid in a single-acting system.  Safety Holding Valve Controls load descent in lifting applications.  Manifold Allows distribution of hydraulic fluid from one power source to several cylinders Needle valve Regulates the flow of hydraulic fluid to or from the cylinders.     Single-acting push application, such as in a press. The hand pump offers controlled cylinder advance, but may require many hand pump strokes in longer stroke applications when the cylinder capacity is 25 ton or above. Single-acting cylinder with longer stroke used for lifting applications. Double-acting cylinder set-up used for lifting applications where a slow controlled descent of the load must be maintained. Double-acting cylinder set-up used in a push/pull application. Two point lifting set-up using single-acting cylinders. Four point lifting set-up using single-acting cylinders, flow control valves and safety valves.
