{"product_id":"industrial-kf4050-drain-valve-timer-controller","title":"Industrial KF4050 Drain Valve Timer Controller","description":"\u003cdiv\u003e\u003cp\u003eIndustrial KF4050 Drain Valve Timer Controller, marketed as Airtek’s Drain Master KF4050, is a timer-driven control device designed to actuate a drain valve in industrial settings. It is described as a single-point control solution that combines timer functionality with a drain valve assembly in a compact package. The unit is powered from 115 VAC, 60 Hz and uses 1\/4\" NPT connections for its plumbing interfaces. According to distributor listings, the KF4050 is discontinued by the manufacturer, so new units may be harder to source and official support could be limited. This model’s designation within the Drain Master family helps distinguish it from other Airtek drain-control products. The combination of a timer interface and valve actuation enables automated drainage operations at a fixed electrical supply, aligning with standard North American electrical conventions and common valve installation practices. As a legacy timer-controlled drain valve solution, it remains relevant for refurbishments, retrofits, or projects that already specify Airtek Drain Master KF4050 hardware.\u003c\/p\u003e\u003c\/div\u003e","brand":"Airtek","offers":[{"title":"New","offer_id":51657160655150,"sku":null,"price":1160.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_dd5446b5-f776-4927-bcd7-4d1b47d9f52f.jpg?v=1769466526","url":"https:\/\/plgautomation.com\/products\/industrial-kf4050-drain-valve-timer-controller","provider":"PLG Automation ","version":"1.0","type":"link"}
