GROCO 2" Bronze Electric Flanged Seacock - 24V

The GROCO 2" Bronze Electric Flanged Seacock – 24V (model FBVE-2000 24V) is a motorized through-hull valve designed for marine engine cooling systems and seawater applications. This 2-inch flanged seacock combines reliable bronze construction with 24V electric actuation, allowing operators to control raw-water intake remotely or automatically—a critical safety feature for preventing engine flooding in unattended operation or emergency shutdown scenarios.

The seacock operates on a gearbox design rated IP-67 (fully sealed against dust and water immersion) and complies with CP-712 standards. Draw from the motor circuit is less than 1 amp, making it compatible with most marine electrical systems without requiring dedicated high-amperage wiring. The unit supports NMEA2000 integration, enabling network control from bridge displays and autopilot systems. Manual valve operation remains available if electrical power is lost, ensuring failsafe access to cooling water. The bronze body resists corrosion in saltwater environments, while the integrated grease zerk fitting allows routine lubrication of internal components to maintain smooth operation across extended service intervals.

This 2-inch seacock is specified for commercial fishing vessels, offshore workboats, and larger cruising yachts where remote engine cooling control is essential. The automatic anti-flooding feature is particularly valuable in uncrewed engine rooms or during extended anchoring periods when manual valve supervision is impractical. UL listing confirms compliance with marine electrical standards. Buyers should verify flange bolt pattern and connection compatibility with existing through-hull plumbing before ordering.

GROCO manufactures this seacock as part of a broader line of motorized seacock sizes (3/4" through 3" standard, with 4" and 5" variants in development), allowing fleet operators to standardize on a single manufacturer across multiple through-hull applications. The 24V version pairs well with modern marine DC systems and is often paired with automatic bilge pumps and engine shutdown interlocks for comprehensive engine room protection.
