Manufacturer: Saginomiya Co., Ltd.
Country of Origin: Japan
Model: GMV-H303GQ9
Product Type: Marine Solenoid Valve
Medium: Oil
Maximum Operating Pressure: 2.26 MPa
Voltage Options:
The GMV-H303GQ9 is an electrically operated normally controlled solenoid valve used to automatically start, stop, or redirect oil flow within marine machinery.
When electrical power is applied, the internal electromagnetic coil actuates the valve mechanism, allowing or stopping fluid flow according to the control system command. This makes it an essential component in modern marine automation systems where reliable remote operation is required.
SM MARINE SERVICE™ regularly supplies this model and compatible Saginomiya valves for ship repair companies, engine overhauls, automation upgrades, and emergency spare-part requirements worldwide.

| Problem | Possible Cause | Recommended Solution |
|---|---|---|
| Valve does not energize | No power supply | Check AC110V/AC121V supply and electrical wiring |
| Coil overheating | Incorrect voltage or continuous overload | Verify supply voltage and replace damaged coil |
| Valve remains closed | Internal plunger seized | Clean internal mechanism and inspect for contamination |
| Valve remains open | Spring failure or mechanical wear | Replace worn internal components |
| Oil leakage | Damaged seal or loose fitting | Replace seals and tighten pipe connections |
| Slow valve response | Dirty oil or contamination | Flush the system and clean the valve |
| Coil burnt | Voltage fluctuation or excessive duty | Install a new genuine coil and verify system voltage |
| Excessive noise | Mechanical wear or unstable pressure | Inspect internal valve assembly and operating pressure |
Routine inspection usually prevents unexpected failures and extends valve life.
For reliable long-term performance:
Proper preventive maintenance significantly increases operational reliability.
Marine engineers continue selecting Saginomiya because of its proven Japanese engineering quality and dependable performance.
