Troubleshooting Hydraulic Proportional Valves The cost of a proportional valve can be as much as 50 percent of the cost of a servo valve of the same size. However, servo valves continue to be used where precise positioning or speed control is required in aircraft, aerospace and turbine generator ... Read More

Direct-operated Proportional Valves Direct-operated proportional valves are used when flow through the valve is approximately 25 gallons per minute (GPM) or less. Two-stage valves, which incorporate a pilot valve and main spool, are used when higher flow rates are required. In order to troubleshoot ... Read More

Proportional valve applications In valve selection, the application is everything. To ensure the best result, specifiers and users must closely consider relevant characteristics of the application that will determine future valve performance. It is important to consider if the application is static ... Read More

Directional Control Solenoid Valves Hydraulic systems often require directional control valves, pressure relief valves and pilot operated check valve when actuators or hydraulic motors are operated. Hydraulic system components such as Cetop valves are used to form a hydraulic circuit. The advantage ... Read More

Pressure-Control Valves Pressure-control valves are found in virtually every hydraulic system, and they assist in a variety of functions, from keeping system pressures safely below a desired upper limit to maintaining a set pressure in part of a circuit. Pressure-control valves are found in ... Read More

Constant Flow Valves Automatic flow control valve that can be manually set for different flow rates. The valve adapts to changing line pressure to maintain a steady flow rate in the downstream piping (see "Principles of Operation") without automation (neither electricity nor an air supply is ...
