The GROCO IBV In-Line Ball Valve delivers reliable marine-grade shutoff and full-flow performance for fuel, water and general plumbing systems. Built in bronze and stainless configurations, the IBV series features female NPT threads, PTFE seats, and a reversible patented handle for easy actuation and long service aboard saltwater vessels.

Key Features

• Marine-Grade Construction: C83600 bronze or #316 stainless steel bodies with corrosion-resistant hardware and UL listing for fuel and water.
• Full Flow & Pressure Rating: Full-flow design with 400 WOG (bronze) and up to 1000 WOG (stainless) for dependable service in demanding marine environments.
• Serviceability & Locking: PTFE seats, grease zerk on 1-1/4″ and larger models for lubrication, and thumb-release locking handle for secure positioning.

GROCO IBV valves are ideal for marine plumbing and seacock installations (fits IBVF) where compact full-flow shutoff is required. The reversible handle with a ratchet-compatible square hole improves access in tight engine-room locations and reduces installation and maintenance time. GROCO’s IBV series pairs with standard NPT fittings and common hose/seacock accessories for straightforward installation aboard recreational and commercial vessels.
