Abstract
A high cycle and speed valve () includes a body (), a valve seat () fixed within the body, and a diaphragm () that moves between a closed position in which the diaphragm is forced against the valve seat, and an open position in which the diaphragm is released from the valve seat. The valve seat includes a static section () that is secured within the body, and a dynamic section () that is compressed by the diaphragm when the diaphragm is in the closed position. The static section includes a radially extending flange () that is received in a recess () formed in the body to secure the static section in the body. The valve includes a body cavity relief space () into which the dynamic section compresses in the closed position. The valve further includes a cap () that has a dry film lubricant layer () that serves as a dry lubricant between the cap and the diaphragm.
