The ports are configured as follows. The right port and the front left port are connected to a "T" inside. they both get pressure from the same valve at the same time. They are ONE way, that is fluid that leaves from them comes back through them. The left rear port is a lowering delay port that allows the rear implement (like cultivators) to be lowered later than the fronts. It is operated by a combination of pressure sensing and control rod position. (Part way in past the hold position of the rod is the delay position) Few applications use that port, leave it alone. By the way it also gets its pressure from the same source and valve. Maximum pressure is about 750 to 800 psi. System capacity is 6 quarts. To use two way cylinders, the open center valve must have its discharge returned to the reservoir sump. The lever control is then pulled out and locked in the raise position to provide pressure for the 2 way valve. Jim
