1.Isolate the control valve from the line pressure, release pressure from both sides of the valve body, and drain the process media from both sides of the valve. If continuous operation is required during inspection or maintenance, install a three-valve bypass around the control valve assembly.

2.Be certain the pipeline flanges are in line with each other and supported.

CAUTION

To avoid damaging valve seating surfaces, make sure the adjacent piping is free of pipe scale, welding slag, and any other damaging material.

3.Inspect the valve body to be sure it is free of foreign material. Make sure the adjacent piping is free of pipe scale, welding slag, and any other material that could damage valve seating surfaces.

4.Measure to be sure the distance between the pipeline flanges is approximately 1/4 inch greater than the valve face-to-face dimension. This will ensure easy installation without distorting the liner (figure 3).

5.For conventional discs, flow may be in either direction; for Fishtail discs, flow must be such that the tail of the disc (as shown in figure 2) will rotate into the downstream side of the valve.

CAUTION

To avoid damaging valve parts, observe the following precautions before inserting the valve in the line.

a.The inside diameter of the mating piping or flanges must be large enough to allow the valve disc to rotate freely into the upstream and downstream piping, or the disc could be damaged. Do not use piping or flanges having an inside diameter smaller than the minimum shown in table 3.

b.The inside of the mating flange must also be small enough to be in full contact with the partial O-rings on the liner faces. Leakage through the flange connections and damage to the liner could
