GROCO 2-1/2" Bronze Electric Flanged Seacock - 24V

The GROCO 2-1/2" Bronze Electric Flanged Seacock - 24V (model FBVE-2500 24V) is a motorized through-hull valve engineered for marine and industrial cooling systems where reliable water intake control is mission-critical. As a mechanic, you'll recognize this as the workhorse component that prevents engine overheat failures and protects against catastrophic coolant loss in boats, emergency generators, and auxiliary power systems. This flanged seacock eliminates manual valve operation during emergency conditions, allowing remote or automated shutdown without crew intervention—a safety feature that separates professional-grade systems from consumer alternatives.

Built from marine-grade bronze for corrosion resistance in saltwater and freshwater environments, the GROCO seacock handles 2-1/2" flow capacity with a 24-volt electrical actuator for dependable valve cycling. The flanged connection design ensures leak-free installation on through-hull fittings and integrates seamlessly with existing cooling loops without requiring expensive adapter kits. The motorized actuation prevents engine damage from intake blockages by automatically isolating the water supply, while the manual override lever allows mechanical operation if electrical power fails—critical redundancy in remote installations where uptime cannot be compromised.

This valve suits vessels and equipment using 24-volt DC systems—common in larger commercial fishing boats, tugboats, and industrial pump stations. Installation requires basic marine plumbing skills: confirm 2-1/2" port compatibility on your through-hull housing and verify 24V power supply availability at the mounting location. The 1-lb compact footprint minimizes space requirements in tight engine compartments while the bronze construction withstands decades of saltwater exposure without galvanic corrosion or mineral buildup. For systems requiring automatic or manual shutdown capability in harsh marine environments, this GROCO electric seacock delivers industrial reliability at a tactical price point.
