Electro-气动定位器
(适用于隔膜阀)
4至20毫安
Electro-Pneumatic Positioner
(for Diaphragm Valves)
4 to 20 mA
可配置在所有高级气动隔膜阀上。当外部4~20毫安控制信号输入转换成线性3~15 psi气动信号输入被采用后,定位器通过调节执行器气源流量来实现控制和调节阀门流量。可提供美国全国电气制造商协会NEMA
4x标准外壳,安装在执行器顶部,带180o可视指示器。
Available for all Premium Pneumatic Actuated Diaphragm
Valves. Positioner is used to control or throttle flow by modulating the
air to the actuator in response to an external 4-20 milliamp control signal
input which is converted to a proportional 3-15 psi pneumatic signal used
by the positioner. Available with NEMA 4x, enclosure mounted on top of
actuator with 180o visual indicator.
小型限位开关模块
(适用于隔膜阀)
单刀双掷(2个)或双刀双掷(2个)
Micro Limit Switch Module
(for Diaphragm Valves)
SPDT (2) or DPDT (2)
可配置在所有高级气动隔膜阀上。模块包括两(2)个辅助机械式限位开关。这些开关是单刀双掷,10安培,125/250伏交流电。开关模块包括180o可视指示器。开关外壳符合美国全国电气制造商协会NEMA
4/4x/7/9标准。
Available for all Premium Pneumatic Actuated Diaphragm
Valves. Module of two (2) auxiliary mechanical limit switches. Switches
are SPDT rated at 10 amp 125/250 VAC. Switch module include 180o
visual indicator. Switch enclosure is NEMA 4/4x/7/9 rated.
