Directional Control Proportional Valves
Parker’s 4-way, 3-position spool-type proportional directional control valves allow for actuator speed and direction control in a single cartridge. Varying current to one of two coils will create a proportional flow out to one of the actuator ports allowing control of speed, acceleration, and deceleration. The second coil controls proportional flow in the opposite direction. AC and DC coil options are available, along with a wide range of connection types. Current Controlled Pulse Width Modulation (PWM) valve drivers are preferred as they adjust for variations in coil temperature and also provide the ability to apply a dither frequency.
GP02 proportional valves are designed to fit in a common C08-4 cavity and they are available in low, standard, or high flow versions. The High flow cylinder spool configuration is capable of flows up to 5.5 GPM (21 LPM). A high flow motor spool is available for flows up to 4.5 GPM (17 LPM.) Standard and low flow versions are offered to allow for greater resolution depending on the maximum flow rate of the application. All GP02 versions are capable of pressures as high as 5000 PSI (350 BAR) and are available with manual overrides.
DSP105 proportional valves are designed to fit in a common C10-4 cavity and they are capable of flows up to 8.5 GPM (32 LPM) and pressures up to 3000 PSI (210 BAR.) Motor and cylinder spool configurations are available and manual overrides are optional.
Combined with Parker’s wide range of Coil options, the 4-way proportional spool valve offering allows for application specific solutions in the most demanding applications and markets including: Power Units, Oil and Gas, Material Handling, Construction, Drills, Presses, Mixers, Agriculture, Balers, Combines, Double Acting Cylinder Control, Bi-Direction Motor Control, Circuit Selectors, etc.
