2. See table 2 and figure 2 for length of studs for the seal protector ring end of V150 and V300 valves. Lubricate the
studs with anti-seize lubricant.
3. Insert flat-sheet line flange gaskets (or spiral-wound gaskets with compression-controlling center rings) that are
compatible with the flowing media.
4. Connect pressure lines to the actuator as indicated in the actuator instruction manual. When an auxiliary manual
actuator is used with a power actuator, install a bypass valve on the power actuator (if one is not supplied) for use
during manual operation.
WARNING
Personal injury could result from packing leakage. Valve packing was tightened before shipment; however the packing
might require some readjustment to meet specific service conditions. Check with your process or safety engineer for any
additional measures that must be taken to protect against process media.
If the valve has ENVIRO-SEAL live-loaded packing installed, this initial re-adjustment will probably not be required. See
ENVIRO-SEAL Packing System for Rotary Valves instruction manual (D101643X012)
for packing instructions.
Installing V200 Valves
Stud length dimensions are shown in figure 4 for the seal protector ring end of the valve. For V200, CL600, the

1. Install the V200 valve using long studs (key 32, figure 4) to connect the two pipeline flanges. Refer to figure 4 for
the size of studs required. Lubricate the studs with anti-seize lubricant.
2. Install two studs in the flanges before you place the valve in the line. Place the two studs so they will contact the
line-centering notches at the bottom of the valve body.
3. Insert flat-sheet line flange gaskets (or spiral-wound gaskets with compression-controlling center rings) that are
compatible with the process fluid.
4. Place the valve on the two studs. Install all remaining studs. Measure carefully to be sure the valve is centered on the
