Stainless steel jacketed gate valve for bitumen

This heavy-duty full jacketed wedge gate valve is manufactured from premium CF8 (SS304) stainless steel, explicitly designed to handle viscous fluids that solidify at ambient temperatures. By welding an outer steel jacket onto the valve body and equipping it with independent flanged heating ports, the valve allows smooth circulation of hot thermal oil or steam to maintain a consistent processing temperature. Its flexible wedge design ensures tight sealing and low operational torque, making it a dependable choice for asphalt plants, oil refineries, and chemical processing facilities.
