3-Way Flow Control Proportional Valves
Brand: Parker HannifinParker selection of normally-closed 3-way flow control proportional valves used with Current Controlled Pulse Width Modulation (PWM) valve drivers have flow capabilities up to 75 lpm (20 gpm) and pressures as high as 210 bar (3000 psi).
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.
