“IN-FLOW” POSITION “OUT-FLOW” POSITION

 

Advantages

Orifice plates installed in this position restrict flow entering the valve port from a cylinder or motor, offering these advantages:
1. Prevents cavitation of a cylinder or motor having an inertia load.
2. Improves control of operation for double or single acting cylinders when lowering.
3. Improves control of rotary cylinders which have inertia loads in both directions. (Use an orifice plate in both cylinder ports.)

Restriction

The lower face of the fitting inserted into the port will limit the upward travel of the orifice plate.


“OUT-FLOW” POSITION”

 

Advantages

Orifice plates installed in this position restrict flow of pressurised oil flowing out of the vane port to a cylinder or motor, offering the advantage of:

1.Improved control for extending single or double acting cylinders or speed of a hydraulic motor.

Restriction

It is necessary to use the retainer (#1A0741)screwed into the port until it bottoms on the port thread, to limit the upward travel of the orifice plate. CAUTION: After installation of retainer, check to see that orifice plate is free to move at least 1/32 inch.
