• the operation of these valves does not depend on the process pressure of the medium fluid nor the flow rate
• they can operate independently of the existing pressure difference ΔP on the valve
• suited to zero pressure differential conditions (ΔP min= 0 bar)
• their design limitation is the value of the maximum pressure difference ΔPMAX that can occur on the valve. It depends on the lifting force of the electromagnet and the nominal diameter of the valve flow orifice (the larger the nominal diameter, the smaller the ΔPMAX value for the same electromagnet)
• with a pressure greater than the maximum differential pressure ΔPMAX, the valve will not work properly (it will suspend)
• short actuation time (from a dozen to several dozen ms)
• high reliability due to the simplicity of the design and a small number of internal parts
• long lifespan – some designs can reach up to several million work cycles
