HIGH CYCLE AND SPEED VALVE |
摘要 |
A high cycle and speed valve (10) includes a body (12), a valve seat (20) fixed within the body, and a diaphragm (24) 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 (40) that is secured within the body, and a dynamic section (42) that is compressed by the diaphragm when the diaphragm is in the closed position. The static section includes a radially extending flange (44) that is received in a recess (46) formed in the body to secure the static section in the body. The valve includes a body cavity relief space (52) into which the dynamic section compresses in the closed position. The valve further includes a cap (26) that has a dry film lubricant layer (58) that serves as a dry lubricant between the cap and the diaphragm. |
