Precautions electric or pneumatic actuators see the corresponding instructions.
( 1 ) , take down the sides of the cover flange end , the valve in the 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 on-line installation ( wiring by electric actuator wiring diagram ) .
( 3 ) , prepared with the former pipe connections must be flushed and cleaned pipeline residual impurities ( these substances may damage the tamper seal labels and ball ) .
( 4 ) during the installation, please do not use part of the valve actuator as the lifting of the lifting points to avoid damage to the actuator and accessories.
( 5 ) The class valve should be installed in a horizontal or vertical direction of the pipe .
( 6 ) , installed near the pipeline can not have bowed to withstand external force or phenomenon , you can use the pipe support brackets to eliminate or deviate from the pipeline .
( 7 ) After the pipe is connected , use the specified torque cross- locking flange bolts.
Operation and Use vehicle seals
( 1 ) , subject to confirmation piping and valves have been washed off before the operation . ( 2 ) , valve operation by the size of the input signal to drive the actuator stem rotation completed : forward rotation 1 /4 laps ( 900 ) , the valve off. Reverse rotation of 1/ 4 turn ( 900 ) , the valve opens. ( 3 ) When the actuator directional arrows parallel with the pipeline when the valve is open ; indicator arrow with a vertical line , the valve is closed .
