It belongs to the \u003cstrong\u003eASCO Series 8290\u003c\/strong\u003e line, which current Emerson literature lists as \u003cstrong\u003eSeries 290\u003c\/strong\u003e, and it is built for on-off control of \u003cstrong\u003eair\u003c\/strong\u003e, \u003cstrong\u003einert gas\u003c\/strong\u003e, \u003cstrong\u003ewater\u003c\/strong\u003e, \u003cstrong\u003eoil\u003c\/strong\u003e, \u003cstrong\u003elight slurries\u003c\/strong\u003e, \u003cstrong\u003ehot water\u003c\/strong\u003e and \u003cstrong\u003esteam\u003c\/strong\u003e. Techs often search for it as an \u003cstrong\u003eASCO solenoid valve\u003c\/strong\u003e because a \u003cstrong\u003esolenoid pilot valve\u003c\/strong\u003e normally supplies its pilot pressure, but the \u003cstrong\u003e8290B010\u003c\/strong\u003e itself has no coil: pilot pressure drives the piston, the stem lifts the disc off the seat, and the valve closes on its own when pilot pressure is removed.\u003c\/p\u003e\n\n\u003cp\u003eASCO's catalog lists the \u003cstrong\u003e8290B010\u003c\/strong\u003e with a \u003cstrong\u003e1-inch orifice\u003c\/strong\u003e, a \u003cstrong\u003e19 Cv\u003c\/strong\u003e flow coefficient, a \u003cstrong\u003e60 to 150 psi\u003c\/strong\u003e air or water pilot pressure range, a minimum operating pressure differential of \u003cstrong\u003e0 psi\u003c\/strong\u003e and a maximum of \u003cstrong\u003e150 psi\u003c\/strong\u003e on both fluids and \u003cstrong\u003esteam\u003c\/strong\u003e. Maximum fluid temperature is \u003cstrong\u003e366°F\u003c\/strong\u003e, ambient and pilot-fluid temperatures run \u003cstrong\u003e15°F to 140°F\u003c\/strong\u003e, and the maximum viscosity is \u003cstrong\u003e2,700 SSU\u003c\/strong\u003e. This is an \u003cstrong\u003eentry-under-the-disc\u003c\/strong\u003e construction, so line pressure is piped to \u003cstrong\u003ePort 2\u003c\/strong\u003e, and the fluid closing the disc from underneath slows the final movement, which helps limit \u003cstrong\u003ewater hammer\u003c\/strong\u003e. The wetted parts are a \u003cstrong\u003ebronze\u003c\/strong\u003e body, \u003cstrong\u003ebrass\u003c\/strong\u003e disc and stuffing box, a \u003cstrong\u003e431 stainless steel\u003c\/strong\u003e stem, \u003cstrong\u003ePTFE chevron\u003c\/strong\u003e stem packing and an \u003cstrong\u003eFKM\u003c\/strong\u003e wiper seal.

The valve works in \u003cstrong\u003eany mounting position\u003c\/strong\u003e, and the factory \u003cstrong\u003eexhaust port plug\u003c\/strong\u003e must stay in place. When a valve is slow, noisy or \u003cstrong\u003efails to open\u003c\/strong\u003e, check the \u003cstrong\u003epilot supply\u003c\/strong\u003e first, since the minimum pilot pressure rises with line differential. A valve that \u003cstrong\u003eleaks past the seat\u003c\/strong\u003e usually has debris or a worn disc seal, and the repair can be done \u003cstrong\u003ein line\u003c\/strong\u003e without removing the body, using the \u003cstrong\u003eASCO rebuild kit\u003c\/strong\u003e number stamped on the nameplate (the service bulletin lists \u003cstrong\u003eC131206\u003c\/strong\u003e for 1-inch bronze valves). On a normally closed valve, pressurize the operator before unscrewing the \u003cstrong\u003estuffing box\u003c\/strong\u003e and keep it pressurized during reassembly, and always depressurize and vent the main and pilot lines first.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eKey Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFail-Closed Shutoff:\u003c\/strong\u003e The \u003cstrong\u003enormally closed\u003c\/strong\u003e design closes when \u003cstrong\u003epilot pressure\u003c\/strong\u003e is lost, and the \u003cstrong\u003ePTFE disc seal\u003c\/strong\u003e provides \u003cstrong\u003ebubble-tight\u003c\/strong\u003e shutoff on compatible media.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHigh Flow Capacity:\u003c\/strong\u003e The \u003cstrong\u003eangle-body\u003c\/strong\u003e flow path delivers \u003cstrong\u003e19 Cv\u003c\/strong\u003e through a \u003cstrong\u003e1-inch NPT\u003c\/strong\u003e connection with a \u003cstrong\u003e1-inch orifice\u003c\/strong\u003e.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eWide Media Range:\u003c\/strong\u003e Handles \u003cstrong\u003eair\u003c\/strong\u003e, \u003cstrong\u003ewater\u003c\/strong\u003e, \u003cstrong\u003eoil\u003c\/strong\u003e, \u003cstrong\u003ehot water\u003c\/strong\u003e and \u003cstrong\u003esteam\u003c\/strong\u003e up to \u003cstrong\u003e366°F\u003c\/strong\u003e with a \u003cstrong\u003e150 psi\u003c\/strong\u003e maximum differential.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eServiceable In Line:\u003c\/strong\u003e The \u003cstrong\u003erebuild kit\u003c\/strong\u003e repair needs no pipe removal, and the \u003cstrong\u003e360°\u003c\/strong\u003e rotating \u003cstrong\u003episton operator\u003c\/strong\u003e makes \u003cstrong\u003epilot valve\u003c\/strong\u003e piping easy to align.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eCommon Questions\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eIs the 8290B10 a solenoid valve?\u003c\/strong\u003e Not by itself.
