Pneumatic insulation jacket single-seat control valve body parameters: Type: Single-seat longitudinal forging ball valve; nominal diameter: 20,25mm; Nominal: ANSI150,300; JIS10,16,20K; PN1.6,4.0Mpa ; adjoining type: flange sealing surface types: FF, RF, RJ, LG, MFM; flange dimension: JIS B2201-1984, JB / T79.1-94 (PN1.6MPa), JB / T79.2-94 ( PN4.0,6.4MPa), ANSI B16.5-1981, HG20594-97, HG20618-97 etc; Material: Steel (ZG230-450), cast stainless steel (ZG1Cr18Ni9Ti, ZG1Cr18Ni12Mo2Ti, ZG316L), titanium; Bonnet : Std (P) 0 ~ + 230 ℃; elongation type I (EI) 0 ~ + 566. Note: Operating temperature ban across all types of material areas of commitment. Gland type: Bolt Clamp; Filler: PTFE impregnated asbestos packing, asbestos braided packing, graphite packing. Electric shut-off valve advantages 1, simple structure, manufacture and maintenance more convenient. 2, the working stroke is small, open and close a short time. 3, sealing, and the sealing surface friction force is small, longer life expectancy. 4, in the form of bellows globe valve body structure has a straight-through DC and right angle. Straight-through is the most common structure two-piece ball valve factory price, but drag its maximum fluid. DC-type fluid resistance smaller Anhui two-piece ball valves, used for solids or viscosity of the fluid contained. Angled body more forged two-piece ball valve for smaller circulation, high pressure shut-off valve. 5, in the process of opening and closing the sealing surface friction than the small two-piece ball valve manufacturer, wear. 6, usually only one sealing surface, the manufacturing process, and easy maintenance. 7, the electric actuator for easy operation.
