ABSTRACT:
A port mounted fluid control valve construction (18) is mounted to a pneumatic cylinder (10) through the first port (31) and second port (37) of the cylinder. The construction includes a removable valve body portion (22) which is detachable from a manifold portion (20). A tube (34) extends from the manifold portion to an adapter body (36). The manifold portion includes a first inlet (42) which extends to a first outlet (50) through a first passage (52). An ear (44) extends in the first passage. A spud fitting (100) which includes cutouts (110) which enables fluid to pass therethrough, is mounted in the first port of the cylinder. The spud fitting includes a threaded opening which accepts a fastener (102). The fastener extends through ear (44) and holds the manifold adjacent the cylinder. The adapter body includes first aperture (122) which is in fluid communication through the adapter body with the tube. A second spud fitting (100') is mounted in the second port of the cylinder. A second fastener (140) extends through the adapter body and is accepted into the second spud fitting to hold the adapter body adjacent the cylinder and in fluid communication with the second fitting. Selectively changing the condition of the valve body enables compressed air to be delivered or exhausted from the ports of the cylinder.
