3至15 psi气动定位器
（适用于球阀和蝶阀）
3 to 15 psi Pneumatic Positioner
(for Ball & Butterfly Valves)

　　可配置在所有高级气动真活接球阀和蝶阀上。当出现外部3~15 psi控制输入信号时，定位器通过调节执行器的气源流量来起到控制或调节阀门流量的作用。可提供美国全国电气制造商协会NEMA 4或4X标准的外壳，并安装在执行器的顶部，并带平面顶部绿/黑指示器或者备选高可视拱形指示器。包括压力表装置，其中一（1）个输入压力表0~30 psi和两（2）个输出压力表0~160 psi，也可提供备选的不锈钢压力表。
　　Available for all Premium Pneumatic actuated True Union Ball Valves and Butterfly Valves. Positioner is used to control or throttle flow by modulating the air to the actuator in response to an external 3-15 psi control signal input. Available with NEMA 4 or 4X rated enclosure mounted on top of actuator with flat top green/black indicator or optional high visibility Dome Indicator. Includes pressure gauge set of one (1) input gauge 0-30 psi and two (2) output gauges 0-160 psi Optional Stainless Steel gauge set available.

Electro-气动定位器
4~20mA, 0~5伏直流电，或0~10伏直流电
Electro-Pneumatic Positioner
4-20mA, 0-5 VDC, or 0-10 VDC

　　可配置在高级气动真活接球阀和蝶阀上。当出现4~20毫安（电流），0~5伏直流电（电阻），或0~10伏直流电（电阻）控制信号输入时，将其转换成能用于定位器的3~15 psi线性气动信号后，这种定位器通过调节执行器气源流量来控制或调节阀门的流量。可提供美国全国电气制造商协会NEMA 4, 4X, 7或本质安全NEMA 7标准的外壳，并安装在执行器顶部，带平面顶部绿/黑指示器或180^o高可视性绿/红拱形指示器。包括压力表装置，其中一（1）个输入压力表0~30 psi和两（2）个输出压力表0~160 psi。可提供备选的不锈钢压力表。
　　Available for Premium Pneumatic actuated True Union Ball Valves and Butterfly Valves. Positioner is used to control or throttle flow by modulating the air to the actuator in response to an external 4-20 milliamp (current), 0-5 VDC (resistive), or 0-10 VDC (resistive) control signal input which is converted to a proportional 3 - 15 psi pneumatic signal used by the positioner. Available with NEMA 4, 4X, 7 or Intrinsically Safe NEMA 7 rated enclosure mounted on top of actuator with flat top green/black indicator or dome indicator with green/red 180^o high visibility. Includes pressure gauge set of one (1) input gauge 0-30 psi and two (2) output gauges 0-160 psi. Optional Stainless Steel gauge set available.

拱形指示器
Dome Indicator

　　可配置在高级气动真活接球阀和蝶阀上。拱形灯塔式高可视性绿/红指示器改善了阀门位置的观察效果。只是指示器本身。注：拱形指示器可以包含在某些定位器或限位开关的选项内。
　　Available for Premium Pneumatic actuated True Union Ball Valves and Butterfly Valves. Dome style beacon with high visibility green/red indicator for improved viewing of valve position. Indicator only. Note: Dome indicators may be included with certain selections of positioners or limit switches.

3通和4通电磁阀
3 & 4-Way Solenoid Valves

　　可配置在高级气动真活接球阀和蝶阀上。这种安装在执行器上的组合阀起着3通或4通导阀的作用。这种3通阀是一种正常关闭提升阀结构以确保关闭紧密。这些阀门设计用于弹簧复位执行器。4通阀门既可作为4通2位结构使用，也可在组装到执行器之前，旋转位于底座的衬垫，使其仅仅作为3通正常关闭结构使用。这种3通结构向执行器弹簧一侧施加源源不断的压力，以防止执行器内部的腐蚀性问题。可购买备选的速度控制器（A-M2）。气源进口连接口径是DN8美国标准锥管螺纹NPT。热塑性塑料合成物外壳符合美国全国电气制造商协会NEMA 4, 4X标准（标准配置）或NEMA 4, 4X, 7, 9标准组合带DN15外螺纹管线连接端口。标准配置为115伏交流电，电压备选件包括230伏交流电，24伏交流电，12伏直流电，和24伏直流电。
　　Available for Premium Pneumatic actuated True Union Ball Valves and Butterfly Valves. This combination valve operates either as a 3-way or 4-way pilot valve mounted to the actuator. The 3-way valve is a normally closed poppet design to insure tight shut-off. These valves are designed for use with spring return actuators. The 4-way valve can be used as either a 4-way 2 position design or a 3-way normally closed design merely by rotating a gasket located in the sub-base prior to assembly to the actuator. The 3-way operation routes the exhaust pressure to the spring side of the actuator to prevent corrosion problems within the actuator. An optional speed control can be purchased (A-M2). Air inlet connection is ¹/₄" NPT. Thermoplastic composite enclosure is NEMA 4, 4X (standard) or NEMA 4, 4x, 7, 9 combination with ¹/₂" male conduit connection. Standard 115 VAC with voltage options of 230 VAC, 24 VAC, 12 VDC, and 24 VDC.
