Abstract
A diaphragm-sealed valve having communication mechanisms operatively connecting neighboring pairs of grooves is provided. Each communication mechanism has a communication port opening in an interface of a valve cap, between the neighboring grooves. The communication mechanism also has a communication conduit extending within the valve cap and connecting the communication port and one of the neighboring grooves. It also has a recess within a valve body aligned with the communication port and with the other one of the neighboring grooves, a flexible sealing surface of the diaphragm being seated within the recess and resiliently biased away from the interface of the valve cap. A plunger assembly is also provided, including plungers movable to push flexible sealing surface towards the communication port.
