Professional Marine Gate, Globe & Butterfly Valve Repair & Lapping in Mombasa
Precise flow isolation and regulation across thousands of engine room pipeline valves are vital for safe ballast transfers, fuel oil separation, and high-pressure steam distribution. When gate valves suffer internal bypassing, globe valve seats become scored by wire-drawing, or butterfly valves fail to seal tightly during a port call at the Port of Mombasa, professional overhaul and lapping are mandatory. Since 2011, Mombasa Ship Services has coordinated comprehensive marine gate, globe and butterfly valve repair and lapping operations for international merchant shipping.
We connect global shipowners with specialized marine pipefitters and mechanical valve technicians in Kenya experienced with high-pressure bronze, cast steel, and stainless steel valve systems. Whether servicing manual handwheel valves or heavy manifold shut-offs, our 24/7 network ensures absolute fluid-tight integrity.
Comprehensive Valve Restoration & Lapping Scope
Valve maintenance demands meticulous hand-finishing and precise mechanical re-machining. Our specialized service scope covers:
Gate & Globe Valve Seat Lapping: Dismantling valve bodies, cleaning internal chambers, and applying coarse-to-fine lapping compounds to grind valve discs and seats back to mirror-finish contact.
Seat Re-Machining & Hardfacing: Boring out severely damaged valve seats, machining replacement seat rings, and executing specialized welding for high-temperature steam applications.
Butterfly Valve Seat & Disc Replacements: Extracting worn elastomer liner seats from butterfly bodies, replacing damaged stainless steel or bronze discs, and renewing operating shafts.
Gland Packing & Bonnet Seal Renewals: Removing hardened asbestos-free packing rings, cleaning stuffing boxes, and installing fresh high-pressure braided packing to prevent stem leaks.
Hydrostatic Pressure Testing: Testing overhauled valves on specialized pressure test benches to verify structural integrity and seat tightness under working pressure ratings.
