Dual piston rack and pinion design for compact construction, symmetric mounting position, high-cycle fife and fast operation, reverse rotation can be accomplished in the field by simply inverting the pistons. Multiple bearings and guides on racks and pistons, low friction, high cycle life and prevent shaft blowout. Modular preloaded spring cartridge design, with coatedspring for simple versatile range, greater safely and corrosion resistance, longer cycle life. Fully machined teeth on piston and pinion for accurate low backlash rack and pinion engagement, maximum efficlency. Stalnless steel fasteners for long term corroslon resistance Full conformance to the latest specifications: IS05211,DIN 3337 and Namur or product inter changeahility and easy mounting of solenoids, limit switches and other aocessodes.柏勒夫气动执行器柏勒夫气动执行器综合了国际最新材料技术、精密加工技术、工业美术设计技术。经过设计、开发、测试、生产和工程运用，该系列执行器具有运行可靠、工作寿命长、可调范围大、防腐性能高、规格多、选型灵活、经济实惠等优点。 BELEF Pneumatic Actuators Incorporate latest mechanical technology, materials available through designing, developing, testing and engineering application, we have obtained a high grade product with the characteristics of reliability, high performance, long cycle life, large adjustment, highest levels of corrosion protection, wide selection of model with easy and economy. 执行器零件、材料一览表 Actuators Parts and Material Table柏勒夫气动执行器柏勒夫气动执行器综合了国际最新材料技术、精密加工技术、工业美术设计技术。经过设计、开发、测试、生产和工程运用，该系列执行器具有运行可靠、工作寿命长、可调范围大、防腐性能高、规格多、选型灵活、经济实惠等优点。 BELEF Pneumatic Actuators Incorporate latest mechanical technology, materials available through designing, developing, testing and engineering application, we have obtained a high grade product with the characteristics of reliability, high performance, long cycle life, large adjustment, highest levels of corrosion protection, wide selection of model with easy and economy. 工作原理和输出扭矩 Operating Principle and Out Torque 柏勒夫气动执行器柏勒夫气动执行器综合了国际最新材料技术、精密加工技术、工业美术设计技术。经过设计、开发、测试、生产和工程运用，该系列执行器具有运行可靠、工作寿命长、可调范围大、防腐性能高、规格多、选型灵活、经济实惠等优点。 BELEF Pneumatic Actuators Incorporate latest mechanical technology, materials available through designing, developing, testing and engineering application, we have obtained a high grade product with the characteristics of reliability, high performance, long cycle life, large adjustment, highest levels of corrosion protection, wide selection of model with easy and economy. 工作原理和输出扭矩 Operating Principle and Out Torque柏勒夫气动执行器柏勒夫气动执行器综合了国际最新材料技术、精密加工技术、工业美术设计技术。经过设计、开发、测试、生产和工程运用，该系列执行器具有运行可靠、工作寿命长、可调范围大、防腐性能高、规格多、选型灵活、经济实惠等优点。 BELEF Pneumatic Actuators Incorporate latest mechanical technology, materials available through designing, developing, testing and engineering application, we have obtained a high grade product with the characteristics of reliability, high performance, long cycle life, large adjustment, highest levels of corrosion protection, wide selection of model with easy and economy. 工作原理和输出扭矩 Operating Principle and Out Torque柏勒夫气动执行器柏勒夫气动执行器综合了国际最新材料技术、精密加工技术、工业美术设计技术。经过设计、开发、测试、生产和工程运用，该系列执行器具有运行可靠、工作寿命长、可调范围大、防腐性能高、规格多、选型灵活、经济实惠等优点。 BELEF Pneumatic Actuators Incorporate latest mechanical technology, materials available through designing, developing, testing and engineering application, we have obtained a high grade product with the characteristics of reliability, high performance, long cycle life, large adjustment, highest levels of corrosion protection, wide selection of model with easy and economy. 工作原理和输出扭矩 Operating Principle and Out Torque柏勒夫气动执行器柏勒夫气动执行器综合了国际最新材料技术、精密加工技术、工业美术设计技术。经过设计、开发、测试、生产和工程运用，该系列执行器具有运行可靠、工作寿命长、可调范围大、防腐性能高、规格多、选型灵活、经济实惠等优点。 BELEF Pneumatic Actuators Incorporate latest mechanica
