Product Introduction: 330130-040-02-05
The 330130-040-02-05 is a Proportional Throttle Cartridge Valve belonging to the NG04 (CETOP 3) size series. This two-way, normally closed valve is designed for screw-in installation into a hydraulic manifold block. It utilizes a proportional solenoid to provide electrically adjustable, metered control of hydraulic flow in one direction, while allowing free flow in the reverse direction. This enables precise and smooth speed control of hydraulic actuators (cylinders or motors). The "-02-05" suffix typically specifies options for the spool type, seal material, and solenoid coil connection.
