An Introduction to Spring Return Lever Ball Valves

Bosseal factory is a professional valve manufacturer for Spring Return Ball Valves, or called Deadman Lever Ball Valves. What is a Deadman Lever Ball Valve? A deadman valve requires manual operation to open, and it automatically shuts off when the handle is released, due to the action of a spring. Without pressure against the spring, the handle will return to its original closed position. A deadman valve may also be referred to as a "spring return handle valve". These valves are...

Valves for FPSO Projects

Bosseal Factory is a professional valve manufacturer for offshore projects, including platforms, vessels, FLNG, and FPSO. What's FPSO? FPSO (Floating Production Storage and Offloading) is a floating production system that processes and stores hydrocarbons extracted from subsea reservoirs. It receives fluids, such as crude oil, natural gas, and water, through risers, then separates them onboard within the topside production facilities. The processed crude oil is stored in onboard storage...
