Pilot Operated, Spool Type, Metric Cartridge – PWK12120WP

The PWK12120WP is a normally closed, spool type, pilot-operated proportional flow control valve.

Together with a pressure compensator, which maintains a constant differential between the inlet pressure (port 1) and the outlet pressure (port 2), it can serve as a proportional flow regulator. Therefore, the energization of the coil reduces or increases an orifice cross-section via the pilot stage and thus controls the effective oil flow.
Moreover, the spring fitted between the main and pilot spools acts against the solenoid force – this force feedback ensures that the flow control spool always maintains a stable position.

Features:

• Reliable and cost-effective proportional control of the flow by controlling the position of the flow control spool using force feedback
• Smooth opening and closing
• Excellent dynamic performance
• Low hysteresis
• Excellent repeatability
• Optional internal damping of the control spool to dampen vibrations in applications prone to vibrations such as lifting equipment
• External surfaces zinc-plated and corrosion-proof
• Coil seals protect the solenoid system
• Wide variety of connectors available
• Also, hardened and ground internal valve components to ensure minimal wear and extended service life
• Finally, different flow rate ranges available
