The SCV Weld In-Line Check Valve is used to accurately monitor direction of flow and pressure in liquid, suction, and hot gas lines. It’s designed for welding directly in-line via socket or butt weld end connections and is available for pipe connection sizes ¾-inch to 1 ¼-inch.
SCI close-coupled end suction pumps and SFI frame-mounted end suction pumps provide reliability and ease in installation for heating, air conditioning, pressure-boosting, cooling water transfer, and water-supply applications.
Specially formulated to provide the high level of atomization required for a spray application, Superwool Sealcoat HT can be applied as part of the primary liner over fiber or refractory surfaces, up to 2 inches (5.1 cm) thick on walls, and up to ½ inch (1.3 cm) of overhead.
Winters Multiport (NVA Series) and Block & Bleed (BBV Series) Needle Valves feature a one-piece, corrosion-resistant 316 stainless steel or carbon steel body, rated up to either 6,000 psi or 10,000 psi.
