Overview of technical parameters of flange full welded ball valves and applicable media and industrial and mining2020-03-31
Application of Dynamic Balance Valve in HVAC Engineering2020-04-03
(1) Flange full-welded ball valve has compact structure, reliable seal, simple structure, and convenient maintenance. The sealing surface and spherical surface are often closed, and it is not easy to be tested by the medium (electric or pneumatic). Use performance).
(2) Installation can only be performed after passing the test (the wiring is according to the electric actuator circuit diagram).
(3) Before connecting to the pipeline, flush and remove the impurities remaining in the pipeline (these materials may damage the valve seat and ball).
(4) During installation, please do not use the actuator part of the valve as a lifting point to avoid damage to the actuator and accessories.
(5) This type of valve should be installed in the horizontal or vertical direction of the pipeline.
(6) The pipeline near the installation point must not have low droop or bear external force. Pipeline brackets or supports can be used to eliminate the deviation of the pipeline.
(7) After connecting to the pipeline, please cross-tighten the flange connection bolts with the specified torque.
