Inflatable seal ball segment valve has been developed to deliver excellent sealing for many types of process equipment operating under atmospheric, full vacuum or pressurized process conditions. Design features of this valve include the fully retractable and inflatable seal that will give dust, liquid and gas tight sealing. Seal does not face the mechanical forces associated with normal sealing methods during opening and closing of the valve, which will give maximum sealing, extended working life, very low maintenance and unobstructed full bore discharging or loading of the product. Sizes range from 4" to 18". Materials of construction include stainless steel, hastelloy and titanium. Bolz - Summix Div. of MPE Group USA LLC 520 Sharptown Rd. Swedesboro, NJ, 08085
