Bellows sealed small-caliber single-seat control valve product introduction Bellows sealed small-caliber single-seat control valve, the valve cover with corrugated structure, which can completely eliminate the process medium leakage from the valve stem clearance of the possibility of bellows seal valve which is one of the salient features of the valve Corrugated pipe element itself deformation and outstanding anti-aging, this electric single-seat control valve completely overcome the packing seal valve usually exists in the aging of the filler and temperature sensitivity and other weaknesses. Second, the use of a double bellows corrugated packing structure, better safety and reliability. Therefore, it is widely used in the automatic control system of rare special media such as highly toxic, corrosive, radioactive and so on. Electric control valve equipped with multi-spring film actuator, its compact structure, the output power. Bellows sealed small-caliber single-seat control valve main performance Leakage: Metal seat: In line with the standard ANSI B16.104IV level, less than 0.01% of rated Cv; Soft seat: meet the standard ANSI B16.104 Ⅵ level, less than rated Cv 10-7; Quick open spool: less than the rated Cv 10-7 Hysteresis: 3% (with positioning device); 5% (without positioning device) Linearity: ± 3% (with positioning device); ± 11% (without positioning device) Note: The standard V-type PTFE packing. Bellows sealed small-caliber single-seat control valve valve components Spool type: single seat spool Flow Characteristics: Metal Sealed - Equal Percentage (% CF) and Linearity (LCF), High Accuracy Cv Values ​​from 0.04 to 14 Flow Characteristics Meets IEC534-2-1976 Flow Characteristics: Soft Seal - Equal Percentage (% TF) and Linearity (LTF) Material: stainless steel (1Cr18Ni9Ti, 1Cr18Ni12Mo2Ti, 17-4PH, 9Cr18, 316L), stainless steel surfacing Tai Lai alloy Corrugated tube material: 1Cr18Ni9Ti, 1Cr18Ni12Mo2Ti, 316L Bellows sealed small-caliber single-seat control valve actuator Type: HA multi-spring film actuator Diaphragm materials: EPDM clip nylon cloth, NBR nylon cloth Spring range: 20 ~ 100,80 ~ 240Kpa Supply pressure: 140 ~ 400Kpa Air source interface: RC1 / 4 " Ambient temperature: -30 ~ +70 ℃
High-purity Graphite, also known as Molded Graphite in the industry, refers to the carbon content of graphite > 99.99%.
