Pneumatic valve should be installed in horizontal or vertical direction

Pneumatic valve installation and maintenance. The installation of the pneumatic valve) , take off the protective cover on both sides of the flange end, under the conditions of valve fully open to wash clean. ） , before installation shall be in accordance with the provisions of signal, Electricity or gas) The engine test ( Prevent because of transportation vibration impact performance) , qualified rear can install ( According to the electric actuator wiring diagram wiring) 。 ) Before, preparation, and pipeline connection, you must wash and clean the pipe residual impurities ( These substances may damage the seat and) 。 ) , during the installation, please don't use valve actuator part as a lifting of the lifting point, in order to avoid damage the actuator and accessories. 。 ) , pneumatic valve should be installed in horizontal or vertical direction. ) Near, installation of pipe with low or bear the phenomenon of external force, can use a pipe support or support to eliminate the deviation of pipelines. ) After, and pipeline connection, please use specified torque cross locking bolt flange connection. , the operation of the pneumatic valve and use) Must be confirmed before operation, piping and valves have been washed. ) , and the size of the valve operation according to the actuator input signal turns the valve stem complete: positive rotation/circle ( °) When the valve is shut off. Reverse rotation/circle ( °) When the valve opens. ) , when executing agency indicating arrow direction parallel to the pipeline when the valve is open; Indicating arrow and vertical pipeline, the valve is closed. 。 Pneumatic valve repair pneumatic valve has a longer service life and maintenance free, will depend on several factors: the normal working conditions and maintain harmonious temperature/pressure ratio, and the reasonable corrosion data
