Valve Knowledge

Motorized ball valve that is by the valve electric device and ball valve two parts. Valve electric device as the power output part, drive the ball valve stem rotation, and then drive the ball core rotation. The medium for switching, regulating, directional, merging, shunting and other control. Has and transmission distance, signal sensitivity and high precision, easy to control, simple wiring and so on.

Low-lift safety valves open gradually (1/40–1/20 of seat throat diameter) with proportional pressure response, suited for liquids and low-pressure gases. Their discharge coefficient ranges 0.07–0.16, featuring compact seats (one size smaller than nominal diameter). In contrast, full-lift valves achieve rapid, full-opening (1/4 throat diameter) via a reverse-flow disk mechanism, delivering 5–10x higher discharge coefficients (0.7–0.8). Designed for steam/gas systems requiring fast pressure relief, they incorporate two-stage opening, snap-action reseating, and enlarged outlets (one size up). Structural distinctions include seat sizing (two sizes smaller for full-lift) and specialized models for high-efficiency applications.
