Arrow indicator on the valve body shows the correct flow direction to guide pipe connections. material and build: constructed from strong, wearresistant materials for a long service life. Precision castings provide a stable structure with reliable resistance and accurate performance. Energy saving and environmentally friendly: normally closed when not energized, reducing energy consumption and saving water and electricity. It supports direct flow control with no ongoing power usage when idle. Safety monitoring and reliable operation: in addition to regulating direction, flow, and speed of the process medium, the valve includes dryrun protection and flow monitoring to help maintain safe, stable operation. Typical use scenarios: Irrigation systems and water treatment setups where energy efficiency and dependable flow control are important. Automated manufacturing lines requiring precise control of coolant, lubrication, or process fluids along with safety monitoring. Chemical or industrial processes where accurate flow management and dryrun protection enhance safety and performance.
