It handles drainage on prep sinks, pot sinks, and three-compartment sinks where a simple, operable drain control is required — a common need in restaurant kitchens, cafeterias, and institutional dishrooms. This rotary valve replaces older T\u0026amp;S models B-3913 and B-3917, making it a direct swap on existing T\u0026amp;S-equipped sinks.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eCast bronze body with rough chrome plating — built for the corrosion and heat exposure common in commercial sink applications\u003c\/li\u003e\n\u003cli\u003eTwist handle with heat-resistant plastic grip opens and closes the drain without tools\u003c\/li\u003e\n\u003cli\u003e2-inch NPT male outlet and 1-1\/2-inch NPT female outlet give flexibility for connection to standard commercial drain lines\u003c\/li\u003e\n\u003cli\u003eRated at 17 GPM flow rate and handles water temperatures from 40°F up to 180°F — sufficient for hot-water sanitizing sinks\u003c\/li\u003e\n\u003cli\u003eIncludes a 3-1\/2-inch snap-in removable strainer and an overflow outlet with cap and sealing washer\u003c\/li\u003e\n\u003cli\u003eCertified to ASME A112.18.2\/CSA B125.2; overall height 4-1\/2 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eA plumber or facilities manager replacing a failed drain valve on a commercial three-compartment sink will find this a straightforward fit — confirmed T\u0026amp;S specs, standard NPT connections, and the accessories needed to complete the installation are all in the box.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable class=\"product-specs\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eDrain Opening Size\u003c\/th\u003e\n\u003ctd\u003e3-1\/2 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOutlet Connections\u003c\/th\u003e\n\u003ctd\u003e2 in NPT male \/ 1-1\/2 in NPT female\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eReplaces Models\u003c\/th\u003e\n\u003ctd\u003eB-3913, B-3917\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e","brand":"T and S Brass and Bronze Works","offers":[{"title":"Default Title","offer_id":45357264535621,"sku":"230216EA1","price":137.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0840\/1021\/files\/T_S_3.5_X2_WASTE_DRAIN_VALVE_TWIST_HANDLE_-main.webp?v=1784330471","url":"https:\/\/www.shopatdean.com\/products\/twist-handle-with-heat-resistant-plastic-grip","provider":"ShopAtDean","version":"1.0","type":"link"}
