    Piece inner ball Q11F type PN16 ~ PN63 thread

  • Product Description
  • [Applications] a ball valve with integral one-piece, two-stage and three-stage. This product is a reasonable structure, beautiful shape. Seat elastic sealing structure, reliable sealing, open and close easily. Installation in the pipeline for opening and closing the pipeline medium, which is characterized by simple structure, the switch rapidly.

    [Works] valve opening and closing member is a sphere. Is the use of stem poppet about the axis of rotation 90. To make the valve flow or occlusion of the ball valve is mainly used for cutting in Gas Transmission Pipeline.

    [Precautions]

    (1) prohibits the cut-off and drain valves operating in the fully open or partially open position, clean or replace the drain valve when the valve is fully closed

    (2) When installing the valve, the ball should be kept in the fully open position. If you need to install in the fully closed position, the ball portion of the exposure must be coated with grease to protect and prevent damage to the sphere spatter on the welding

    (3) before the valve repair, you should first close the valve, drained cavity pressure relief valve through the valve at the bottom, to ensure a safe range in pressure inside the valve

    (4) The discharge valve device has a drain hole, the operator must observe when operating the outlet direction, preventing exudates wounding

    [Maintenance]

    (1) once to place the seat groove chamber cleaning once a year, to ensure the free movement of the valve seat

    (2) To ensure the safe operation of the valve, fully open, fully closed valve operation three times, check seat injection valve, check valve injection valve, valve or drain valve to ensure the valve is in the exact location, clean valve grease valve

    (3) If the drain valve when the valve stop excretion excretion, first check whether the valve is fully closed six state seats greasing hole utilize the full capacity of the sealant injection to each seat. Then drain valves

    (4) If the valve leaks, valve seat can be cleaned, rinsed. First check whether the valve is fully locked, can be taken to operate the valve to fully closed; followed by the limit check whether the actuator can be adjusted properly, may be appropriate to adjust the limit actuator

    (5) If a leak at the stem, stem seal may be a fault. If the pipeline can be taken to replace the valve stem with pressure uppermost O-ring or by injection hole of the valve stem, injecting a small amount of sealant. If the pipeline without pressure. You can also split the packing box, replace all the internal and external stem seals, valve stem can be replaced if necessary
