Detailed Product Description: | ZXZQ-O O-regulating valve Pneumatic Overview ZXZQ-O O-pneumatic regulating valve, is the introduction of foreign advanced technology on the basis of special design, well-made products. Smart control and positioning, and supporting electrical valve positioner input signal and 4-20mADC 0.4 ~ 0.7MPa air to control operation, to realize the pressure, flow, temperature, level and other parameters of the regulation. It is a compressed air driven, driven spool valve stem in the valve body can rotate 90 ° fully open - fully closed the action. Sealing performance of the product into its metal seal and soft seal. With a compact, compact, reliable, good sealing, easy maintenance, easy installation, flexibility and other advantages. Particularly suited to the medium is thick, containing particles, fiber nature of the occasion. Can be widely used in petroleum, chemical industry, teaching equipment, light industry, high-voltage equipment, pharmaceuticals, paper and other industrial automatic control system for remote centralized control or local control. ZXZQ-O O-regulating ball valve pneumatic Nominal diameter: 15 ~ 200mm Nominal pressure: PN1.6 4.0 6.4MPa Connection: flange by JB78-59 JB79-59 Material: WCB, HT200, ZG1Cr18Ni9Ti, ZG0Cr18Ni12Mo2Ti, PTFE lining, CF8 (304), CF8M (316), CF3M (316L) Temperature range: ambient temperature -20 ℃ ~ +180 ℃ The temperature of -40 ℃ ~ +350 ℃ Packing: V-type PTFE packing, impregnated with PTFE packing, Asbestos braided packing, flexible graphite.
