Hydraulic Relief Valves
Relief valves are the most common type of pressure-control valves. The relief valves’ function may vary, depending on a system’s needs. They can provide overload protection for circuit components or limit the force or torque exerted by a linear actuator … Continue reading
Pressure Control Valves
A pressure-control valve may limit or regulate pressure, create a particular pressure condition required for control, or cause actuators to operate in a specific order. All pure pressure-control valves operate in a condition approaching hydraulic balance. Usually the balance is … Continue reading
Pilot-Operated Relief Valves Hydraulic Circuits
A pilot-operated relief valve can be used to unload the pump at low pressure during periods between work cycles. The schematic in Fig. 3.10 shows a solenoid-actuated directional control valve connected to the remote pilot port on the side of … Continue reading
