ANSI Class 300 2 Inch Flanged Check Valve , Swing BS 1868 Check Valve

Description:

   Check valves are automatically actuated.they are opened and sustained in the open position by the force of velocity pressure, and closed by the force of gravity. Seating load and resultant tightness is dependent upon back pressure. The disc and associated moving parts may be in a constant state of movement if the velocity pressure is not sufficient to hold the valve in a wide open and stable position. 

  Cast steel swing check valves can be furnished with outside lever and adjustable weight when so ordered. With the lever and weight mounted so that the weight assistes the disc in closing, the valve closes more rapidly when flow stops, thus minimizing reversal of flow and resultant surge and shock. With the lever and weight mounted to balance the weight of the disc, the valve becomes more sensitive to low inlet velocities.

  Swing check valvs are used to prevent reversal of flow in horizontal or vertical pipe lines. in Vertical lines, or for any angle from hirzontal to vertical , they can be used for upward flow only.
