Parker Cylinder Port Availability

Parker cylinders can be ordered with a variety of different port types and positions. The standard port location is Position 1, as indicated in Figure 1. Cushion adjustment needle valves are at position 2 and 4 (or 3), depending on the mounting style. See Table A for mounting styles in which the head or cap can be rotated at no extra charge. To order, specify by position number. The cushion adjustment needle valves rotate accordingly in such assemblies, as their relationship with the port position does not change.
