These valves are used to operate pumps at the minimum load in an accumulator circuit or in a high-low pump circuit. In an accumulator circuit,…
These valves maintain hydraulic pressure in a hydraulic system or load backpressure on a cylinder. If the inlet pressure exceeds a preset level, flow is…
These valves control the sequential operation of two or more actuators. If the inlet pressure exceeds a preset level, they deliver effective pressure to the…
These valves are a combination of a pilot operated relief valve and a small solenoid operated directional valve. Sending electrical signals to the directional valve…
These valves consist of a balanced piston for bypassing excess flow in hydraulic circuits and a pilot that controls the piston motion and pressure. Placed…
These valves are small and have a simple structure for their capacity. However, they are likely to exhibit high- pressure override (a pressure characteristic observed…
These pumps have pistons installed at right angles against the pump rotating shaft in a plane including the shaft. The pistons reciprocate with alternately moving…
These pumps operate by rotating two or three screw shafts, which are aligned and engaged in parallel, to continuously convey a volume structured with screw…
These pumps operate with two gears engaged with each other and rotating to feed a hydraulic fluid from the suction area to the discharge area.…
Vane pumps can be transformed to the unbalanced type by making the center of the round cam ring eccentric to the rotating shaft; this type…
