Product Overview
The WANDFLUH CVUA-6-PDW is a direct-acting, solenoid-operated poppet valve engineered for leak-free directional control in demanding industrial hydraulic circuits. Manufactured by Wandfluh AG, a recognized Swiss specialist in high-pressure hydraulic valves, the CVUA series utilizes a seated poppet design rather than a sliding spool, delivering zero internal leakage in the closed position and reliable sealing even after extended periods of inactivity. With a nominal size of 6 (NG6 / CETOP 3 interface), the CVUA-6-PDW functions as a 2/2 or 3/2 style seat valve depending on configuration, making it suitable for holding, clamping, isolation, and pilot control functions where pressure integrity is critical. The “PDW” designation indicates the specific solenoid voltage, connector type, and manual override configuration supplied for this variant. Its compact cartridge-style construction allows direct installation into manifold blocks or standard subplate bodies, supporting high working pressures typical of modern industrial power units.

Engineering Features & Advantages
- Zero Leakage Sealing: The seated poppet design eliminates internal leakage across the closed valve, ensuring load holding and pressure retention without drift — a decisive advantage over spool-type directional valves.
- Direct-Acting Response: Solenoid force acts directly on the poppet, providing fast, deterministic switching independent of pilot pressure availability.
- Contamination Tolerance: The simple seat geometry is less sensitive to particulate contamination than close-clearance spool valves, extending service intervals in real-world industrial systems.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with robust solenoid encapsulation and hardened seat surfaces.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original WANDFLUH standards, allowing straightforward retrofit into existing hydraulic systems without rework.
