John Gjerde

John Gjerde supplies innovative vent check valves for floating and offshore installations. The valves are engineered for reliable, safe operation across a wide range of vessel types, including aluminum high speed patrol boats, tugs, ferries, offshore vessels, high tech FPSOs, and drilling vessels.

John Gjerde serves Drilling, FPSO Owners, Vessel Owners, and Shipyards. The product range spans from high speed patrol boats to high tech FPSOs, matching valve design to vessel-specific operating conditions.

Vent check valves protect tank and system integrity by controlling venting and preventing backflow. On floating units, this supports safe pressure management during normal operation and in rough sea states.
