General service control valve

          General service control valve is widely used for non-severe flow control of most liquids, steam, gases and most other fluids. It is especially designed for general working condition for controlling fluid. It is the key safety equipment in the pipeline recirculation system.

          General service control valve provided by seafly century limited is especially designed for non-severe application working conditions and control a wide variety of relatively clean liquids and gases at general working application.

          Typical application and industry include bellows.
