Valves are a fundamental part of most hydraulic systems. When properly selected, they can provide many years of trouble-free operation controlling flow or pressure, controlling transients, handling trapped air problems, preventing backflow, avoiding cavitation, noise and vibrations and many other tasks. However, all too often, valves create operational problems.
