ABSTRACT:
There is disclosed a pinch valve of greatly improved performance. The pinch valve has a housing with end plates having apertures forming a through passageway to receive a flexible conduit. The housing is split through the apertures of the end plates, into two halves, forming upper and lower saddles that are detachably interconnected to permit assembly of the housing about a flexible conduit, thereby eliminating cutting or breaking of the flexible conduit to insert or to relocate the pinch valve. The upper half of the housing carries a stationary bar or anvil and a circular cam actuator moves the valve member through a complete, 360 degree, rotation in a sinusoidal action movement. This action gives the valve a great mechanical advantage at shutoff position, permitting use of a small, lightweight valve structure.
