Page 13: Preparation Before Installation
Bolt the valve to the mating flange using the proper size fasteners. See the Recommended fasteners table in this section. ITT recommends you use studs to ensure the full thread engagement of tapped holes. Lubricate stainless steel fasteners to prevent galling. -
Page 14: Check After Installation
4.5 Check after installation 4.5 Check after installation Operate the actuator to have the valve full open or closed for several times smoothly to make sure it is in good condition. Check the tightness at the connection face between the pipe and valve. Valve shall not be used to replace the blind flange for the piping pressure testing. -

Page 16: Adjust The Packing
5.4 Adjust the packing 5.4 Adjust the packing The packing may require some adjusting after the line pressure is up to normal. Stroke the valve a few times. Tighten the packing gland bolts just enough to stop the leakage. Over tightening the packing may cause undue pressure against the gate making the valve difficult to operate and causing packing wear. -
Page 17: Packing Dimensions
5.6 Replace the seal NOTICE: Position the packing gland so it is centered on the gate, but not touching the gate. Improper installation may result in premature packing failure. Replace the packing gland nuts and tighten them so that the packing gland sets the packing. NOTICE: Do not tighten the packing gland nuts completely. - Page 18 5.6 Replace the seal Open the valve fully. Remove the yoke, topworks, and packing gland from the valve: Remove the yoke fasteners and gate clamp fasteners. Lift off the yoke and topworks. Remove gland fasteners and packing gland. Lift out the gate, clean it, and smooth out any marred or rough surfaces with a scotch-brite pad. The gate should be free of grooves and scratches.
