It features a diaphragm and piston valve type with a normally closed configuration. Constructed with a brass body and PTFE seals, this valve operates within an ambient temperature range of 14 to 140 degrees Fahrenheit and can handle fluid temperatures up to 210°F for hot water and 300°F for steam. It accommodates a 1\/2 inch nominal pipe size with NPTF inlet and outlet connections, and includes an coil for actuation. The valve provides automated control of fluid flow with a flow coefficient (Cv) of 4.7.\u003c\/p\u003e  \u003cp\u003eKey Features: \u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e- Valve Design: Diaphragm, Piston with 2-Way, 2-Position operation\u003c\/li\u003e \u003cli\u003e- Operation Type: Pilot Operated; Valve Starting Configuration: Normally Closed\u003c\/li\u003e \u003cli\u003e- Media Compatibility: Hot Water and Steam\u003c\/li\u003e \u003cli\u003e- Maximum Ambient Temperature: 140°F; Minimum Ambient Temperature: 14°F\u003c\/li\u003e \u003cli\u003e- Maximum Fluid Temperature: 210°F Water, 300°F Steam\u003c\/li\u003e \u003cli\u003e- Maximum Operating Pressure Differential: 150 psi for hot water, 50 psi for steam\u003c\/li\u003e \u003cli\u003e- Body Material: Brass with PTFE seal material\u003c\/li\u003e \u003cli\u003e- Coil Enclosure: Watertight without junction box; Coil Insulation Class: H\u003c\/li\u003e \u003cli\u003e- Electrical Connections: 1\/2 in conduit with 18 in leads; Voltage: 24V DC; Wattage: 15.6 W\u003c\/li\u003e \u003cli\u003e- Nominal Pipe Size: 1\/2 in with NPT thread type and NPTF inlet and outlet connections\u003c\/li\u003e \u003cli\u003e- Dimensions: Overall Height 4-3\/32 in; Length 2-7\/8 in; Width 2-1\/4 in\u003c\/li\u003e \u003cli\u003e- Environmental Rating: Indoor, Outdoor, Hazardous, Washdown\u003c\/li\u003e \u003cli\u003e- Flow Capacity: Cv of 4.7; Orifice Diameter: 1\/2 in\u003c\/li\u003e \u003cli\u003e- Standards: CSA, UL Listed\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASCO","offers":[{"title":"Default Title","offer_id":43320148328542,"sku":"8220G405","price":455.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0663\/7151\/8558\/files\/Z19LLufo9x4_ad030985-7095-4be2-a442-20504e9c9698.jpg?v=1789254674","url":"https:\/\/nationalboilersupply.com\/products\/asco-8220g405-solenoid-valve-2-way-2-position-normally-closed-1-2-in-pipe-size-24-v-dc","provider":"National Boiler Supply","version":"1.0","type":"link"}
