GROCO 3/4" Bronze Tri-Flanged Ball Valve/Seacock

The GROCO 3/4" Bronze Tri-Flanged Ball Valve/Seacock (FBV-750) is a heavy-duty fluid isolation valve engineered for marine and industrial fluid systems where reliability under demanding conditions is non-negotiable. Cast from bronze, this tri-flanged ball valve delivers corrosion resistance and durability in saltwater, freshwater, and fuel applications where standard steel valves would deteriorate rapidly. The field-reversible handle allows operators to orient the closed position for optimal installation geometry, accommodating clockwise or counter-clockwise operation based on system layout.

This 3/4" ball valve includes a grease zerk fitting for on-system lubrication and a drain plug, both standard on larger sizes. The zerk fitting accepts standard grease applicators and functions as a secondary drain point when needed. The handle features a square drive hole to accept standard ratchets and tools, enabling rapid operation under field conditions. The tri-flanged configuration provides three mounting points, distributing loads and offering flexible installation across deck-mounted, bulkhead-mounted, or inline piping scenarios. Weighing 1.7 lbs with compact dimensions of 5 x 4 x 7 inches, this valve balances structural integrity with practical portability for vessel system retrofits or repairs.

The 3/4" bore suits mid-size fluid systems on recreational vessels, commercial fishing boats, industrial water handling, and fuel distribution networks. Bronze construction makes it the standard choice where cost and performance align—brass alloys resist dezincification and pitting that plague steel valves in marine duty. This product serves operators who demand proven materials and established marine hardware standards over experimental alternatives.

GROCO is recognized in the marine industry for seacocks and through-hull fittings that prioritize reliability in salt-air environments. The bronze tri-flanged ball valve reflects that heritage, offering a full-flow, low-pressure-drop design that integrates into systems requiring manual isolation without complexity. Marine hardware this proven sells for good reason: it works when it counts.
