3-Piece Stainless Steel Threaded Ball Valves
Jacketed 3-Piece Stainless Steel Ball Valve
A jacketed 3-piece stainless steel ball valve is a stainless steel ball valve with a heating jacket surrounding the valve body, through which steam, hot water or thermal oil circulates. Thanks to the jacket, the valve body remains continuously heated; it prevents fluids that solidify or thicken when cooled—such as chocolate, bitumen, resin, oil and adhesive—from freezing inside the valve.
In addition to full bore models, 3-way L-type jacketed models are also available. Supplied in AISI 304 and AISI 316 options, pressure classes PN16–PN40 and sizes DN15–DN100, they are used in food, chemical and petrochemical processes.
