The Model LT & LTF Valves will operate satisfactorily when installed in any position. These valves may be used as Line Check Valves, permitting full flow of hydraulic oil in one direction only.
Models S & SM offer a simple method of directing system flow to one or the other of two separate lines. An example of this is the operation of two single-acting cylinders, independent of each other, with one three-way control valve. Since the S & SM spools are of open-crossover design, they should be shifted before pressure is applied.
Economically designed for effective control of air and hydraulic fluids where frequent adjustment is not required.
