GROCO 2" Bronze Electric Flanged Seacock - 12V

The GROCO 2" Bronze Electric Flanged Seacock with 12V motorized operation is a critical through-hull valve assembly designed for marine engine cooling systems and raw water applications. This flanged seacock combines motorized convenience with manual failsafe operation, ensuring reliable water intake control whether power is available or not—a dual-mode design essential for offshore and coastal vessel operations where engine flooding prevention is non-negotiable.

The 12V electric actuator draws less than 1 amp of current, minimizing electrical load on battery systems during extended operation. The gearbox housing meets IP-67 submersion ratings and complies with CP-712 standards, protecting internal mechanisms from saltwater corrosion and spray intrusion. NMEA2000 compatibility enables integration with modern marine automation systems, allowing remote operation from helm displays or navigation consoles. Bronze construction resists corrosion in saltwater environments, while the included grease zerk fitting allows field lubrication without disassembly. UL listing confirms compliance with marine electrical safety standards.

This 2-inch flanged seacock is engineered for vessels requiring automatic engine protection combined with manual override capability. It suits cruising sailboats, offshore fishing vessels, and commercial marine applications where unattended cooling system management reduces operational risk. The automatic feature prevents raw water intake when the engine is off, eliminating the potential for siphoning seawater into the engine block—a catastrophic failure mode in marine propulsion systems. Operators facing rough seas or emergency conditions can always access manual control regardless of electrical status.

GROCO seacocks are established standards in marine engineering for reliability and longevity. The 2-inch bore accommodates higher flow rates than smaller valves while maintaining the through-hull flange interface common across modern marine plumbing. Part number FBVE-2000 12V specifies the 12V variant; 24V options and larger 3-inch to 5-inch bores are available for different system configurations and power architectures.
