Import Ejection Oil Solenoid Valve — Buy in wholesale FOB from Supplier in China

The EJECTION OIL SOLENOID VALVE model MFZ6-90YC is a direct-acting, 2-way solenoid valve designed for hydraulic oil control in generator unit lubrication systems. It operates at 220V AC with a maximum pressure rating of 25 MPa and features a brass body with stainless steel internals. The valve has a 6.3 mm orifice diameter and a standard NPT 1/4 inch thread connection, matching common industrial hydraulic interfaces. Its sealing system uses a nitrile rubber O-ring and a wave spring mechanism to maintain tight shut-off under dynamic pressure fluctuations.

This valve is typically used in coal-fired and hydroelectric generator systems where precise oil flow control is critical to bearing lubrication and thermal regulation. The valve body material conforms to ASTM B16.1 for brass castings, and the solenoid coil is rated IP65 for dust and splash resistance. While the supplier does not specify exact tolerance ranges, standard industry tolerances for such valves are ±0.05 mm for orifice dimensions and ±0.1 mm for mounting flange alignment. The valve is compatible with ISO 6743-4 HLP 46 hydraulic oil and similar viscosity grades.

Buyers typically source this valve for maintenance of medium to large generator units, especially in power plants across Southeast Asia and Africa. Packaging is in protective foam-lined cardboard boxes, with 10 units per carton. Minimum order quantities are not stated but are typically negotiated based on project scale. Delivery is FOB Deyang Port, with lead times averaging 15 to 25 days after payment confirmation. Buyers should request a material certificate and pressure test report before shipment.
