VALVES; TAPS; COCKS; ACTUATING-FLOATS; DEVICES FOR VENTING OR AERATING

Description

F16K covers mechanical devices that control, regulate, or direct fluid flow and gas exchange in piping systems and machinery. This includes valves of all types (gate, ball, check, relief, directional control), taps and cocks for manual or automated flow control, float-actuated mechanisms for level sensing, and devices for venting or aerating fluids. The classification encompasses both the structural design of these components and their actuation mechanisms, whether manual, pneumatic, hydraulic, or electrical, across applications ranging from industrial processes to domestic plumbing and HVAC systems.
