3 Way Flow Control Proportional Valves

Parker’s selection of 3-way flow control proportional valves provide repeatable and precise controls to circuits requiring proportional flow control through 3 lines in a normally-closed configuration. These valves are capable of handling flows up to 75 lpm (20 gpm) and pressures as high as 210 bar (3000 psi). These valves can achieve pseudo pressure due to the pressure drop across the spool orifices, but an external compensator can also be used if finer control is required, making these valves ideal for variable flow sharing applications that need exact control with to ability to close off one leg of the circuit completely. Parker’s 3-way flow control proportional valves can pair with any Current Controlled Pulse Width Modulation (PWM) valve driver and can be used on a variety of mobile and industrial applications within the agriculture, construction, and manufacturing markets. Markets: • Agriculture • Construction • Miscellaneous Industrial • Miscellaneous Manufacturing • Miscellaneous Mobile Features/Benefits: • One piece cartridge housing • Regulates flow proportionally to input solenoid current • Non-magnetic spool and housing assembly • Precise factory setting   Value Statement: Parker DFA125 pressure compensated, proportional flow regulators replace multiple valves thus simplifying hydraulic circuits, reducing manifold size and complexity. Applications: • Applications requiring precise controls • Variable flow applications • Priority flow sharing Additional Technical Insight: Recommended to be used with a Current Controlled Pulse Width Modulation (PWM) valve driver.
