220V AC 3/4" NC Electric Solenoid Valve, Alloy Body

[RELIABLE NORMALLY CLOSED DESIGN] This electric solenoid valve operates as a normally closed type, meaning it remains closed until power is applied. When a 220V AC power supply is applied, the valve opens to allow flow and closes instantly when the power is removed. This built-in safety design is ideal for automated systems requiring controlled fluid release and preventing leaks when not in use. [DURABLE ZINC ALLOY CONSTRUCTION] Made from a high-quality zinc alloy, the valve body offers exceptional strength and corrosion resistance. It reliably handles pressures up to 0.8 MPa (116 PSI) and operates smoothly in fluid temperatures ranging from -5°C to 80°C. This robust construction ensures long-lasting performance in demanding water, oil, air, and gas applications. [VERSATILE APPLICATION COMPATIBILITY] Designed for use with piping carrying water, air, gas, and low-viscosity, non-corrosive fluids. The 3/4-inch (DN20) BSPP thread size and 20 mm flow orifice provide a large flow capacity, making it an ideal replacement valve for irrigation sprinklers in central heating systems and industrial fluid control setups. [Important Installation Guidelines] For best performance and longevity, install this solenoid valve indoors in a horizontal position in a dry environment. A clear arrow on the valve body indicates the correct flow direction for proper pipe connection. If outdoor use is required, you must protect the coil component from water exposure to prevent electrical damage. [OPTIMIZED FOR INTERMITTENT OPERATION] This valve is designed for short-term intermittent use rather than continuous duty. For reliable operation and to prevent overheating, keep each Continuous power-on period of less than 30 minutes. This makes it perfectly suited for applications such as timed irrigation cycles or periodic system flushing where prolonged operation is not required.
