Hydraulics: Control Valves (Online Course)

A single malfunctioning valve can make an entire system break down. This course teaches students how various valves function and affect system operation. Course objectives include: Describe the basic structure and operation of normally closed and normally open pressure control valves Describe the uses for relieve, unloading, sequence, counterbalance, brake, pressure-reducing valves, and flow control valves Explain how pressure compensation enables a flow control valve to maintain a desired flow rate regardless of pressure fluctuations Describe the function and basic operation of one-way, two-way, three-way, and four-way directional control valves Identify methods of spool actuation for directional control valves.
