10-15). What do the three terms position. way. and port mean
when describing directional control valves?
11-4). A static face seal groove with a mean diameter of 4.000
in. is to be recessed in a flange and covered with a face plate. If
the O-ring has a free cross section of 0.125 and is to
be given an initial squeeze of 25%, what are the dimensions of the

Please answer and teach me I will appreciate it. Thank You so
