MECHANICAL ENGINEERING AND FABRICATION
This water intake pipe work, with a bronze gate valve (at top) was replaced with a stainless skin fitting and ball valve. For those mechanically minded... The sealing arrangement with gate valves relies on a wedge that seats at the bottom of the valve body.
The main cause of leakage is foreign matter trapped under the wedge preventing the wedge to seat properly. By using ball valves the sealing action is created by rotation rather than compression and therefore a ball valve with its ‘shearing’ action ensures no foreign matter can be trapped. Stainless steel ball valves provide a double sealing capability due to having a nylon seal on each side of the ball. Instant opening and closing is also provided. Why not replace all your hull penetrations with ball valves for peace of mind.
