workingpressureofhigh pressure ball valvescan be up to 15000 psi. High pressure ball valvesare mostly used in applications under high pressuresuch ashydraulicsystems, so they are known ashydraulic ball valvesalso.
Flow-control valvesinclude simple orifices to sophisticated closed-loop electrohydraulicvalves that automatically adjust to variations in pressure and temperature. The purpose offlow controlin a hydraulic system is to regulate speed.
