A quarter-turn valve includes a valve body having an inlet, an outlet, and a diaphragm adjacent arranged in said valve body for movement between a closed and opened position for restricting and controlling fluid flow. The valve further includes an input shaft for receiving a torsional input load in a closing direction and a torsional input load in an opposite opening direction. A cam is mounted on the input shaft. The cam transforms input loads to linear output loads that flex the diaphragm between its closed and opened positions.

Quarter-turn diaphragm valve

An overload protection device for a manual hoist lever including a pressure hub, an outer hub, a brake nut, and a dowel pin. The pressure hub includes a radially extending flange and a cantilevered boss having a threaded outer surface with an axial groove. The outer hub includes a central opening, a tapered inner surface, and a flange contact surface which frictionally contacts the radially extending flange of the pressure hub. The brake nut is disposed in the central opening of the outer hub between the outer hub and the boss of the pressure hub, and includes a frusto-conical outer surface that frictionally contacts the tapered inner surface of the outer hub, as well as a threaded inner opening with a corresponding axial groove, the threaded inner opening being sized to threadingly engage the boss. The dowel pin is received within a receiving hole formed upon alignment of the axial groove of the boss and the corresponding axial groove of the brake nut. The outer hub preferably includes a plurality of ratchet gear teeth and the frictional resistance of the overload protection device adjustable by tightening or loosening the brake nut.
