Tailored control valves for solar applications Because of the unfavorable operating conditions in which they operate, control valves have a significant influence on the safety and availability of a solar power plant. Here are a few considerations to keep in mind when evaluating piping system components.
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.
A solar cell (also known as a photovoltaic cell or PV cell) is defined as an electrical device that converts light energy into electrical energy through the photovoltaic effect. A solar cell is basically a p-n junction diode.
Photovoltaic cells are devices that convert solar energy into electrical energy, commonly used in solar panels to capture sunlight and generate electricity.

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 first part will focus on how specially tailored control valves can overcome the challenges inherent in solar power production. Solar energy is a viable alternative to fossil fuels and nuclear power. It’s safe, climate-friendly and plentiful, especially in the Earth’s sun belt.
