Pinch Valve
Pinch valve operation can be either mechanical or automatic. A mechanical pinch valve is a multi-turn valve, meaning the handwheel (Figure 2 labeled A) turns more than 360° during the opening and closing of the valve. The valve's normal position is open (Figure 3 labeled A). While the handwheel turns, the valve stem (Figure 2 labeled B) …
