Installation Manual for Sure Flow Equipment Dual Door Check Valves

The valve is inserted between two companion flanges with gaskets on contact faces. Stud bolts that will span the valve and flanges are installed, and the joint made up in the same manner as any flanged joint. The Sure Flow wafer check valve flange diameter has been sized such that the valve centerline will be in alignment with the center of the companion flanges when it is cradled by the stud bolts. The normal installation of the Sure Flow wafer check valve is for horizontal flow with the pin vertical, which allows the plates to swing correctly. The valve should be installed a minimum of 7 to 10 pipe diameters away from any turbulence. The valve may be installed for vertical flow-up or vertical flow-down. When installed in a vertical pipeline, the valve may require a special torque spring or lightweight plates according to the direction of flow, the line pressure, or the line medium.

When removing the valve from the line, only one half of the stud bolts need to be removed, and the others just loosened.

In order to ensure correct installation, the direction of flow is indicated by arrows cast into the side of the body.
