Pilot & Spool Control

Model 4WEH16D50/CG24N9Z5LET is an electro-hydraulic (pilot-operated) directional valve in the 4WEH16 family, directly interchangeable with the Bosch Rexroth 4WEH16 series. A small pilot stage drives the main NG16 spool, allowing large flows - 300 L/min and above - to be switched by low-power solenoid signals. Pilot and drain options (internal/external, E/T/ET) match the original configuration codes, so the control-oil supply and leakage return logic of your existing system are preserved without redesign.

Mounting & Electrical

4WEH16D50/CG24N9Z5LET mounts to the ISO 4401-07 (NG16) interface with the same bolt pattern and porting as the original, so no manifold changes are required. The pilot solenoid uses a Z5L DIN 43650 connector (IP65) with DC 24 V or AC 220 V coils and an optional manual override. Main stage working pressure reaches 31.5 MPa; the cast-iron body is machined to +/- 0.005 mm tolerance for leak-free sealing under heavy cyclic loads.

Quality & Reliability

Every 4WEH16D50/CG24N9Z5LET unit is 100% factory-tested - electrical function, internal leakage and peak pressure up to 31.5 MPa - with batch-traceable records, and holds Intertek certification. It is backed by a 1-year replacement warranty and an 8-year design service life. As with the full YXCHK range, standard orders ship within 7 working days from Ningbo Port, with 1-piece MOQ and OEM/ODM options available.

Where It Fits

4WEH16D50/CG24N9Z5LET is built for massive industrial power systems: marine deck machinery (winches and anchors), mining crushers, metallurgical lines and large press installations where solenoid size and pilot flow demand an electro-hydraulic stage. The high-strength cast-iron housing and hardened spool handle continuous heavy-duty cycling.

Typical Applications

  • Marine & offshore - anchor winches and deck machinery
  • Mining equipment - roof supports and crushers
  • Metallurgy - steel production line drives

Quality & Standards

Every YXCHK valve is 100% factory tested (electrical, leakage and max pressure) before shipment. Mounting patterns comply with ISO 4401 / DIN 24340 international standards, and the design follows the ISO 4401 hydraulic valve interface specification, matching the original Bosch Rexroth and Yuken dimensional standards.

Products are Intertek certified for high-pressure reliability, backed by a 1-year replacement warranty and 8-year design service life. Standard orders ship from Ningbo port within 7 working days.
