Swing Check Valve
  • A swing check valve is a type of check valve that uses a disc to prevent backflow. The disc is mounted on a hinge and is held in the open position by a spring. When fluid flows in the forward direction, the disc is forced open by the pressure of the fluid. When the flow stops or reverses, the disc swings shut and prevents backflow.

    Swing check valves are typically used in applications where there is a need to prevent backflow, such as in pipelines, tanks, and vessels. They are also used in applications where there are high pressure or flow rates.

    Manufactured as per the following Design, Face to Face and End Connection Standards. ASME, ANSI, AS, BS, API etc.

his sweater is a bulky, fairly heavy winter sweater that will be awesome for the office or casual wear. The fabric is very silky soft. It’s nice and snuggly! I can’t wait for it to get cool enough to wear it! Sanjeev Garg | 27 Aug, 2021
