Proportional Control Valves

Proportional Control Valve
Proportional Control Valve

In line with our goal to provide advanced technologies to the hydraulic industry, Fluid Logic Inc. offers proportional control valves, for the variable electronic control of flow and pressure, position and speed within a circuit. We provide standalone units as well as the integration of proportional controls into our directional control valves. Components include ceramic poppet and seat, servo motor, electronic controller, electro-mechanical thrust actuator, servo controllers for speed and position, advanced touch screen display, linear position transducer (LVDT), and (PLC). Open loop and closed loop programming options are available according to customer application, with offered Temposonics sensors for precision position control.

Proportional control valves are composed of stainless steel, with a ceramic and stainless steel seat. Our valves have a pressure rating of 5,000 psi (320 bar), and are available in sizes DIN 10 to 250 (.5" to 10" diameter). 2 way, 3 way, and 4 way configurations are available, with acceptable media type including HWCF, low viscosity hydraulic fluids, kerosene based roll coolants, water glycols, synthetic fluids, inverted emulsions, water 95/5, and mineral oil. Fluid Logic's proportional valves are ideal for pipe testing, coil car traverse cylinders, hoist cylinder speed and position controls, and forging and extrusion press speed control applications. For more details about our proportional control valves, or other products and services please see the table below or contact us directly.
