A line of zero-leak solenoid actuated directional valves for reliable actuation of single- or double-acting cylinders has been introduced by Interface Devices, Inc. The D03 Series valves can be used with most hydraulic pumps to maintain pressure for long periods without replenishing the pressure supply. This prevents the hydraulic supply from consuming energy or generating heat. These 3- and 4-way directional control valves are poppet-style and solenoid actuated. They are ideal for applications with pressures up to 5000 psi where pressure and flow are intermittent and they are designed for mounting to an international standard valve subplate (D03, NG6, ISO 03). The 49 mm width allows for mounting multiple valves on standard 50.8 mm centers. This series of valves is constructed of premium components, including 7075-T651 extruded aluminum bar bodies and hardened and ground steel poppets and seats. Backup rings and O-ring seals are PTFE and polyurethane. The valves are compatible with most standard industrial grade hydraulic fluids and operate at temperatures from -54C to 104C.
