Years of worry free inexpensive operation are virtually guaranteed because there are no moving parts. This lightweight compact unit is easily installed on any existing or new application. A flow control valve in the oil line controls the cylinder advance speed. Rapid extend stroke to approach the work.

Flow controls in the lines to the cylinder from the oil tanks not shown on drawing will meter the oil as it exits each cylinder port. Air over oil reservoirs wall mount. Ldi click for map. Automatic switch to controlled rate when resistance is met and pressure builds up to the point where a fabco air rv sequence valve actuates the 2 way shut off valve forcing fluidflow through the speed controlling needle valve.

Several cylinder suppliers offer air oil tanks that consist of a cylinder tube with two cylinder end caps held on the tube with tie rods. Try a duramaster air over hydraulic tank today and see the difference. Air over oil tanks do not intensify the oil pressure regardless of the tank s diameter or length. The sequence is as follows.

Single air oil tank used for 2 speed work stroke with shock control. Figure 3 1 shows a single tank air over oil system with an air valve piped to an air over oil tank to power the rod end with its other port connected directly to the cylinder cap end.
