Other chapters consider the pressure in a hydraulic system, which can be quickly and easily controlled by devices such as unloading and pressure regulating valves. This book discusses as well the importance of control valves in pneumatic and hydraulic systems to regulate and direct the flow of fluid from compressor or pump to the various load devices.
The directional control valve controls the direction of the hydraulic oil flow. The direction of the hydraulic oil determines if the cylinder will either extend or retract. Hydraulic oil returns from the cylinder, through the control valve and filter, and back to the reservoir.
Load Cylinder Relief Valve Prime Mover Pump Strainer File Size: 2MB. However, some companies identify the flow control in Figure as a throttle valve. These companies say a flow control must have a bypass and be pressure-compensated as shown in Figure Figure Pressure- and temperature-compensated flow control.
When a hydraulic actuator needs accurate speed control, use a pressure-compensated flow. A 2-spool directional control valve with built-in relief controls the lift and bucket cylinders of the loader.

This valve body contains the internal porting to direct the fluid flow. The outer ports on the valve block are threaded to allow hoses and lines to be connected to it. Control valves are an increasingly vital component of modern manufacturing around the world. Properly selected and maintained control valves increase efficiency, safety, profitability, and ecology.
The Control Valve Handbook has been a primary reference since its first printing in. Proportional directional valves control running-away loads because most spool designs control flow to and from the actuator. If the actuator is a hydraulic motor or a double rod-end cylinder, volume at the inlet and outlet is the same.

Hydraulic Valves. Complete your custom hydraulic system or make a quick repair with these hydraulic valves.
Safety features like relief valves are essential for all systems, while other products like divider-combiner valves are a smart upgrade for specific applications. Control and direct the flow of any hydraulic fluid with the right. There are two types of valves, directional control valves and pressure relief valves.
Directional control valves manage the flow path of the fluid in the system. Pressure relief valves protect the system plumbing and components against pressure overloads. They also limit the output force exerted by rotary motors and cylinders. These valves open.
This chapter discusses linear and rotary actuators. Linear actuators are used to move an object or apply a force in a straight line. Rotary actuators are the hydraulic and pneumatic equivalent of an electric motor.
The third type of actuator is used to operate flow control valves for process control of gases, liquids or steam. Parker offers a wide range of hydraulic valves for a variety of mobile and industrial applications.

Hydraulic Valves- control pressure, direction and flow rate of the hydraulic fluid.
Actuator - converts hydraulic energy into mechanical energy to do work. An actuator can be a rotary hydraulic motor or a hydraulic cylinder. Hydraulic motors and cylinders are used on agricultural, construction and industrial equipment. Hydraulic Control Systems is a powerful tool for developing a solid understanding of hydraulic control systems that will serve the practicing engineer in the field.
Throughout the book, illustrative case studies highlight important topics and demonstrate how equations can be implemented and used in the real world/5(7).
directional control valves, flow control valves, etc. Pneumatic circuits have the following functions: 1. To control the injection and release of compressed air in the cylinders. To use one valve to control another valve. Displayed as Pneumatic circuit diagram.
Brake valves to control hydraulic motors with over-running loads. Figure depicts brake valves (sometimes called over-center valves) piped in the lines between the motor and the directional valve.
To control the motor in both directions of rotation, install two brake valves as shown.
