灵活、可靠的执行机构
　　Flexible, Reliable Actuation
　　由于采用模块化设计机构，美国尼伯科电动和气动执行机构能够灵活容易地应用到新的或现存改装的阀门上。电动和气动执行机构具有ISO标准安装设计结构，应用范围广泛。
　　Engineered with a modular approach, NIBCO‘s electric and pneumatic actuation systems give you the flexibility to actuate new valves or to retrofit existing valves with unprecedented ease. Both electric and pneumatic actuation systems feature an ISO standard mounting design, assuring long-term industry acceptance.

　　气动执行机构系统
　　Pneumatic Actuation Systems
　　适用于大多数角行程阀门，使用程度理想，美国尼伯科NDA和NSR气动执行机构在紧凑的结构里提供非常的开启和关闭扭矩。这些执行机构始终如一的满足高扭矩的要求，甚至可以应在阀门长时间关闭的环境。
　　Ideally suited for most quarter-turn valves, NIBCO NDA and NSR pneumatic actuators offer exceptional starting and ending torque in a compact design. They consistently meet the demand for high torque, even in applications where the valve has been closed for an extended period.
　　由于采用长期、无润滑使用寿命设计机构，美国尼伯科NDA和NSR执行机构结合O形环和TFE密封构成一个经久耐用、低摩擦密封。它们适用于广泛工业领域内的开启关闭操作，调节或比例控制，包括化学加工和纸浆造纸，石油炼制和生产，造船以及商业建筑等应用领域。
　　Engineered for a long, lubrication-free service life, NIBCO NDA and NSR actuators combine O-rings and TFE seals to create a durable, low-friction seal. They are designed for either on-off duty, modulation or proportional control in industries ranging from chemical processing and pulp and paper, to petroleum refining, production industries, marine applications, and commercial construction applications.

　　电动执行机构
　　Electric Actuation Systems
　　适用于自动化或计算机控制的流体控制系统，美国尼伯科电动执行机构具有非常的灵活性和便利性。特别适用于不容易操作阀门的环境，这些执行机构能够替代人工流体控制调节，节省人工成本。
　　For automated or computer-controlled flow control systems, NIBCO electric actuators offer exceptional convenience and flexibility. Ideal for applications where the valve is not readily accessible, these actuators provide a labor-saving alternative to manual flow control regulation.
　　美国尼伯科电动执行机构采用齿轮减速电机原理，因此开启和关闭速度控制在两秒至一分多钟范围内。配置可逆电机，适用于连续工作，美国尼伯科电动执行机构能够提供最大的扭矩输出和更长的使用寿命。它们具有过热保护功能，保护电机免受极端温度的影响。
　　NIBCO electric actuators operate on the gear reduction motor principle, which allows opening and closing speeds ranging from two seconds to one minute or longer. With reversible motors that are rated for continuous duty, NIBCO electric actuators provide maximum torque output and longer life. They also feature thermal overload protection to safeguard the motor from extreme temperatures.
