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

The GROCO 1-1/2" Bronze Electric Flanged Seacock - 24V is a marine-grade through-hull valve engineered for saltwater cooling systems, bilge management, and engine intake applications aboard vessels. Designed for operators who demand reliability in harsh marine environments, this 24V motorized seacock automates critical fluid control without manual intervention, reducing crew workload and improving engine protection during normal operation and emergency shutdowns. The bronze construction withstands corrosion in saltwater exposure, making it an essential component for commercial fishing boats, pleasure yachts, and industrial marine platforms.

This unit delivers motorized valve operation via a robust 24V electric actuator that opens and closes the 1-1/2" flanged orifice with precision timing, preventing engine overheat damage and unintended water ingestion when systems cycle offline. The marine-grade bronze body resists galvanic corrosion inherent to saltwater environments, while the flanged design ensures secure mounting to through-hull fittings without reliance on hose clamps alone. A manual override lever provides failsafe operation if 24V power is lost, allowing crew to isolate seawater circuits during emergencies or port maintenance without disassembly.

Best suited for marine engineers retrofitting cooling systems or original equipment builds requiring automatic seawater isolation, this seacock integrates seamlessly into 24V vessel electrical architecture (matching most marine diesel auxiliary systems). The 1-1/2" port diameter accommodates mid-sized cooling loops and strainer circuits aboard vessels between 30–80 feet, while the flanged connection ensures leak-free integration without pipe dope or thread sealant compromise. Installation requires basic through-hull access and 24V DC circuit wiring; consult your boat's electrical schematic and ABYC standards for integration into existing panel-mounted controls or timer-based automatic shutdown logic.
