ABSTRACT:
A valve is disclosed including a body, a bonnet, a flexible diaphragm adapted to be positioned between the bonnet and the body, and an actuator mechanism. The flexible diaphragm has a central portion and a peripheral portion surrounding the central portion, wherein the peripheral portion includes a substantially rigid ring extending continuously through or on the peripheral portion. The body has an input port, a central portion, and an output port. The actuator mechanism is 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. The bonnet is adapted to house the actuator mechanism, and the actuator mechanism is positioned in the bonnet.
