Miniature And Compact Grooved Butterfly Valve with Tamper Switch UL 2in

Miniature And Compact Grooved Butterfly Valve with Tamper Switch UL

Structurally, the valve disc is centrally positioned within the pipeline. A stem (rod) penetrates the disc and connects to an actuator mounted externally on the valve. Rotating the actuator rotates the disc to either a position parallel to the medium flow (fully open) or perpendicular to it (fully closed), thereby regulating the on/off control of the medium

Unlike ball valves, the disc of a butterfly valve remains permanently in the flow path—even when fully open, it does not disengage from the flow channel. Consequently, this design inherently induces a certain degree of pressure drop, a characteristic that makes butterfly valves more suitable for applications where strict pressure loss requirements are not a primary concern. In contrast, ball valves typically exhibit minimal pressure drop when fully open, as their ball cartridge is completely retracted from the flow path.
