Yamaha YSC-10080-30-00 Pressure Relief Valve YSC100803000

Description:

The Yamaha YSC-10080-30-00 is a pressure relief valve used in marine engine cooling and thermostat housing systems to regulate internal pressure and protect engine components from overpressure conditions. It is commonly installed in Yamaha sterndrive and inboard marine engines where maintaining proper cooling system pressure is critical for safe operation. Maintenance teams, marine technicians, and OEM service providers purchase this valve for replacement of failed components, preventative maintenance, and restoration of proper cooling system function.

Applications:

The Yamaha YSC-10080-30-00 pressure relief valve is used in marine engine environments where cooling system pressure must be controlled to prevent damage.
