The Asco 8221G035 Solenoid Valve (8221G35) is a high-capacity solenoid valve designed for large-scale water control systems that demand efficient flow management and surge protection. Its 2 ½-inch NPT connection and large orifice size allow for greater water volume handling, making it ideal for industrial and municipal applications. The slow-closing feature minimizes pressure spikes, ensuring system stability and reducing wear on piping infrastructure.
