The present disclosure relates to a valve including a valve body defining an inlet port and an outlet port. The valve also includes a first diaphragm arranged and configured for opening and closing a fluid flow path between the inlet and outlet ports. The valve further includes a second diaphragm cooperating with the first diaphragm to enclose a chamber formed within the valve body. The valve is closed by applying an actuating pressure to an exterior side of the second diaphragm such that the second diaphragm mechanically causes the first diaphragm to close the fluid flow path between the inlet and outlet port.
