1) Remove the protective cover on both sides of the flange end at the valve is fully open state to wash clean. 2) the signal should be required prior to installation (electric or gas) in the whole test (to prevent vibration from transport performance), after passing the wire installation (wiring by electric actuator wiring diagram). 3) Prepare the front pipe connections shall be flushed and cleaned of impurities remaining in the pipeline (these substances may damage the seat and ball). 4) During the installation of the filter network, please do not use the actuator portion of the valve lift lifting points as filter maintenance, to avoid damage to the actuator and accessories. 5) The class of valve should be installed in a horizontal or vertical direction of the pipe. 6) installed near the pipeline should not be downcast external force or phenomenon, you can use the pipe brackets or supports to eliminate deviation from the pipeline. 7) and pipe connections, please use the specified torque cross locking flange bolts. Electric valve actuators and ball by constitute electric ball. A pipeline pressure components in industrial automation process control, typically used for remote media channels on and off (turn on, off medium) control. Electric valve standard GB / T21465-2008 "valve term" is defined as: opening and closing parts (ball) driven by the stem, and around the valve stem axis of rotational movement. Mainly used to cut off or connected to the line of media filters, can be used to adjust and control the fluid, which has a strong V-ball between hard sealing ball core with its V-shaped carbide hardfacing metal seat The shear force brass filter, especially for fiber-containing tiny solid particles and other media materials. Flanged ball valve into electric power, electric wafer ball valve, electric welded ball valve, electric threaded ball. The seal in the form of electric valve seal is also divided into soft, hard seal electric ball. Brass filters, filters, electromechanical England by City Electrical Equipment Co., Ltd. of England.
