ABSTRACT:
A metal diaphragm valve is disclosed, which has an improved locking mechanism capable of locking the valve in closed position. The mechanism comprises a roller that is snugly disposed in a cutout formed in the bonnet made integral with the knob which drives the diaphragm through a reciprocating plunger. The roller is made rotatable on a horizontal plane with the bonnet which is in turn turned by the knob. When the knob is turned, for an angle of 90 degrees, from the fully-opened position of the valve to the fully-closed position, the roller slips into a groove formed in a stationary member provided in the bonnet. When the roller fits into the groove, the operator can tactically feel the drop and hear a clicking sound, confirming that the valve is closed.
