The pneumatic actuator is a double acting cylinder. The standard supply pressure for the pneumatic cylinder is min. 6 bar. The cylinder size is determined according to the process line pressure. The pneumatic actuator is also available in special materials for aggressive conditions. FENGCHI heavy duty Pinch Valve is a long-lasting and ideal valve, which is specially designed for shut-off and control applications involving abrasive or corrosive slurries, powders, or granular substances. Size range: 15~2000mm, ½~84in Pressure range: 1-10MPa, 1:2 safety factor, which means bursting pressure is 2 times higher than the operating pressure. Material of valve body： DN15~200 (carbon steel, ductile iron, aluminum alloy, stainless steel-casting process)； DN250~2000 (45#steel, stainless steel welding technology )； Material of valve sleeve： NR, EPDM, CR(chloroprene rubber), NBR, butyl rubber, FPM, Hypalon rubber.
