Cartridge valve KWE5 series

electrically-actuatedflow controlsteel

Overview
KWE5A/G series are electric pilot control valves designed to control pilot circuits in construction machinery and industrial vehicles operated outdoors. KWE5A models use an aluminum casing; KWE5G models use a steel casing. Typical configurations include 1 to 4 cartridge valves; other arrangements are available on request.

Features

• Easy wiring: cartridge-type solenoids accept a plug-in connector for single-action electrical connection.
• Compact installation: multiple valve block housings for cartridge solenoid valves accommodate different installation constraints.
• Simplified piping: many valve block housings provide a single P-port and a single T-port.
• Carry-over port: optional carry-over port supplies hydraulic power to additional circuits.
