The Asco 8221G009 Solenoid Valve (8221G9) features a larger 1 ¼ inch NPT port and higher flow capacity (Cv 13), making it ideal for applications requiring increased water flow. Its slow-closing snubber effectively reduces water hammer in larger pipe systems where pressure surges are more significant. Built with a robust brass body and NBR seals, it ensures reliable performance in demanding industrial and municipal environments.
