Claim:
A valve, comprising: a body having an input port, a central portion, and an output port; a bonnet; a flexible diaphragm having a central portion and a peripheral portion surrounding the central portion, the peripheral portion of the flexible diaphragm being adapted to be positioned between the bonnet and the body, the flexible diaphragm being formed of a flexible elastomeric or flexible plastic material; a rigid ring extending continuously through or on the peripheral portion of the flexible diaphragm, the rigid ring being formed of a rigid non-corrosive metal or a rigid and non-reactive plastic; an actuator mechanism operatively coupled to the diaphragm for moving the diaphragm between an open configuration wherein the input port and output port are in fluid communication with each other, and a closed configuration wherein the diaphragm blocks the central portion and prevents fluid flow between the input port and the output port; and wherein the bonnet is adapted to house the actuator mechanism.
