O-rings are used to seal all kinds of devices to keep them operating and safe. They do so by keeping necessary fluids in hydraulic systems and unwanted fluids and contaminants out.

The purpose of a flow control valve is to regulate the flow rate in a specific portion of a hydraulic circuit. In hydraulic systems, they’re used to control the flow rate to motors and cylinders, thereby regulating the speed of those components.

Counterbalance valves are used in hydraulic systems working with an overriding (run-away) or suspended load. They are designed to create back pressure at the return line of the actuator to prevent losing control over the load.

The purpose of pressure-reducing values is to keep the secondary pressures correct in branches of hydraulic systems. Most pressure-reducing valves are open and 2 way this allows the pressure to flow freely until they reach further downstream where there is a set pressure.

Pressure relief valves are used in hydraulic systems to limit the system pressure to a specific set level. If this set level is reached, the pressure relief valve responds and feeds the excess flow from the system back to the tank. Note: the pressure relief valve is a normally closed pressure control valve

Poppet valves are used in hydraulic systems. They are commonly controlled through solenoids and can be set to be either normally-closed or normally-open in their de-energized states. They are also used as check valves to provide one-way flow and as relief valves to guard against over pressure.

Hydraulic breather filters remove solid particle from incoming air to ensure the hydraulic system continues to perform as intended for the duration of its expected service life. As indicated above, air breathers play a critical role in hydraulic systems.

A hydraulic cooler is a device designed to prevent oil used in hydraulic systems from overheating. This is a critical function in hydraulic systems, as overheating of the oil can lead to a drop in system efficiency and excessive wear of the system components in general due to reduced oil viscosity.
