The fundamental working principle of a gas pressure reducing valve is relatively straightforward. The valve comprises several key components, including an inlet and outlet, a diaphragm or piston, and a spring mechanism. When high-pressure gas enters the valve, the diaphragm or piston moves, adjusting the opening of the valve seat to regulate the flow of gas. The spring component exerts a force that balances the pressure within the system, allowing only a predetermined lower pressure to pass through.
In conclusion, electric valves are integral components in modern fluid control systems, offering numerous advantages such as automation, precision, and energy efficiency.
