Product Overview
The Parker D3W020HNJW42 is a high-performance, direct-operated solenoid directional control valve from Parker Hannifin’s renowned D3W series. Engineered for precise control of hydraulic fluid flow direction in industrial systems, this 4-way, 3-position valve features a robust spool-type design with a nominal flow capacity of 20 L/min (NG6 / CETOP 3 / ISO 4401-03 size). The D3W020HNJW42 utilizes a wet-armature solenoid configuration, ensuring reliable, fast-response actuation with minimal pressure drop and excellent repeatability. Its spring-centered spool returns to the neutral position upon de-energization, providing fail-safe operation in critical hydraulic circuits. This valve is a direct-fit, drop-in replacement for OEM Parker D3W series installations, delivering the precision metering, low leakage, and long service life expected in demanding industrial environments.
