HYDAC PWK06J proportional directional flow control valves

HYDAC Australia has released the PWK06J series of proportional directional flow control valves.

The three-position, four-way valve has a screw-in cartridge and is solenoid operated. The product is compact, at a fraction of the size of similar proportional directional valves, and is said to provide low-flow accuracy and repeatability.

The valve’s internal leakage is less than 100 cc/min, hysteresis less than 6%, linearity within 3% and repeatability within 3%. The 12 W ‘D’ or ‘P’ type coils are available in all voltages and connections.

The valve is also 1000-hour salt, fog and rust protected and can be used with a DW06V inlet compensator for optimal pressure-compensated operation to provide constant flow at any given control setting regardless of variations in pressure.

Use of a 200 psi compensator allows high flow up to 4 gpm, while a 100 psi compensator allows for precise control at lower flows. For less precise applications, the valve may be used without a compensator.

The series is fully interchangeable with the WK06E and J ON/OFF valves, allowing flexibility for machine builders. The compact, high-power coils allow multiple valves to be installed in a very small space (for example, six functions can be housed within an 20 cm long block).
