Accessories for pneumatic stroke and rotary actuators – CLASSIC and ELEMENT process valves

The modular designed accessory option package is the comprehensive addition to the Bürkert process valves with pneumatic,

 linear or quarter-turn actuator (Types 2000, 2002, 2012, 2030, 2031, 2031K, 2050, 2652, 2655, 2658, 2672, 2675). 

The ? exible, easily accessible concept of modular accessories 

has been designed to cover individual application requirements in a cost-effective way.  

The design has been optimized for easy installation (retro-? tting), commissioning and  operation.  

? Complete modular designed accessory program 

preferably with actuator in upright position Protection type IP65 and IP67 according to EN 60529,

利于流動的二位二通閥體由紅銅或鑄造的不銹鋼構(gòu)成，能夠?qū)崿F(xiàn)高流量值。

在此類免維護的堅固閥門上，可以加裝各種用于顯示位置、限制沖程或進行手動應(yīng)急操作的配件。

不銹鋼或紅銅外殼，帶有套頭、夾緊式或焊接式接頭

高流量

從外部控制的斜座閥由一個氣動的活塞驅(qū)動裝置和一個二通閥體構(gòu)成。

The electrical position feedback Type 8697 is optimised for integrated mounting on the CLASSIC 20XX series.

 Mechanical or inductive limit switches register the position of the valve und gives an electrical  feedback signal to the control system.  

Besides the electrical  position feedback signal the position of the valve is  visually shown  via LEDs.
