{"product_id":"asco-8221g11-valve","title":"ASCO 8221G11 Valve","description":"\u003cdiv\u003e\u003cp\u003eASCO RedHat 8221G11 is a 1-1\/2 in NPT, two-way (2-position), normally closed slow-closing solenoid valve designed for water service, featuring a brass body and a 120 V AC coil rated for 60 Hz with about 11.6 W of power. It is pilot-operated to minimize water hammer, making it suitable for hydronic heating, cooling, and general water-distribution applications where clean, controlled shutoff is required. The valve handles a differential pressure range from 5 to 150 psi and is rated for fluids up to 180°F (82°C); it is specified for water service only, not for steam. Wetted parts include a brass body with PTFE and NBR seals, a PTFE\/NBR core tube, a 302 stainless steel piston, 430F stainless steel springs, and a shading coil made of stainless steel or brass. In practical terms, this model provides reliable, low-noise operation in residential and light commercial water systems where slow closing helps protect piping and fixtures during shutoff. \u003c\/p\u003e\u003c\/div\u003e","brand":"ASCO","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46276479975658,"sku":null,"price":87.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-076.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/asco-8221g11-valve","provider":"GTG Hardware","version":"1.0","type":"link"}
