The hydraulic pressure is used to hold the valve open and compress a powerful, self-contained spring. If valve closure is required, hydraulic pressure is released and the spring quickly closes the valve, preventing further loss of product. These are just two examples of the hundreds of viable applications for solar-powered valve actuators.
An important factor when considering solar power for valve actuation applications is the potential for leaks. If the equipment is not properly designed for the environment, operating conditions, and pressure and temperature cycling, hydraulic systems can leak. In addition, the fluid itself needs attention.
The solar PV array provides power supply to the control unit, converting it to a two-phase supply using converters and fed to the linear stepper motor. Due to the two-phase supply, electromagnetic coils A and B energized alternately to create downward linear motion. Figure 11.
A scheme of a localized irrigation system with two-way latch-type solenoid valves with limited stroke length, two ports of water flow (inlet and outlet), and two switching states (open or closed) to start/stop the controlled water flow, which is usually in open condition so that the valve closes on power failure [ 23, 94 ], is shown in Figure 12.
An electromagnetic device called a “Linear Solenoid” turns electrical energy into a mechanical pushing or pulling force or motion for rapid ON and OFF operation and mainly comprises an electromagnetic coil, a plunger (armature), and a spring.
The convectional solar panel’s mechanical cleaning structure is called a gantry structure [ 24] and is operated by two rotary actuators. Using telescopic actuators offers the possibility of reducing the use of one rotary actuator for reduced overall cost and energy consumption.
