Generally, the flow rate of pilot-operated solenoid valves is larger than that of direct-acting solenoid valves.Ģ. The direct-acting solenoid valve is usually used in small caliber and low pressure environment while the pilot-operated solenoid valve is suitable for large caliber and high pressure occasion. Are there any differences between them?ġ. The ATO-2W series solenoid valves have two valve types, direct-acting with port size G1/4”, 3/8” and pilot-operated with port size G1/2, 3/4 inch etc. Tips: D irect-acting vs pilot-operated solenoid valve Clear water flow direction mark, convenient to install. Diaphragm structure, general purpose for air and water, reliable operation.Ĥ. Solid and thick solenoid valve with smooth surface.ģ.

High quality copper coil, corrosion resistance and good stability.Ģ. It is widely used in the areas like mechanical, textile, medical, food processing and so on. The NC valve is open when the solenoid is energized and it is closed when de-energized. Operational pressure range: Air, Water, Gases: 0 to 101 PSI Oil: 0 to 72 PSIįlow capacity: 7.Two-port (2/2-way) Normally Closed brass electric solenoid valves are general purpose for controlling flow of air, water and oil with DC 12 Volt, DC 24 Volt, AC 110 Volt, AC 220 Volt. Customers chose this general purpose valve for: do-it-yourself projects, moderate temperature applications, harsh chemicals, flow control for irrigation systems, reverse osmosis systems, or to control flow of propane gas. Suitable for use with hot or cold water, gas, air, very low viscosity fluids (< 20 cst), oils and hydrocarbons, e.g., gasoline, kerosene, or diesel fuel. Solid normally closed (N/C) electric solenoid valve is constructed with a high-quality stainless steel body, two-way inlet and outlet ports with three-quarter inch (3/4') female threaded (G) connections, and heat and oil resistant Viton gasket.
