These valves set hydraulic circuit pressure equal to or below a pressure in the main circuit. When the outlet pressure reaches a preset level, the…

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…
The principle of converting pressure into kinetic energy and then reconverting this energy into a controlled pressure can be utilized as a control means. The…
The direct acting and pilot operated relief valve have a different pressure vs. flow curve although both of them perform the same function. The pilot…
The figure above illustrated the working principle of direct acting relief valve. When the hydraulic force Fh equals spring force Fs, the valve cracks open,…
