I-VIC300MS / Vic-300® MasterSeal™ Butterfly Valves / Installation and Maintenance Instructions
INSTALLATION INFORMATION
Series 761 and 461 Butterfly Valves are designed with grooved ends for use with Victaulic grooved pipe couplings. Refer to the instructions, supplied with the Victaulic coupling or Vic-Flange® Adapter, and the notes in this section for installing Series 761 or 461 Butterfly Valves into the piping system.
DO NOT INSTALL SERIES 761 OR 461 BUTTERFLY VALVES INTO THE SYSTEM WITH THE DISC IN THE FULLY-OPEN POSITION.
• When using Series 761 or 461 Butterfly Valves for throttling service, Victaulic recommends positioning the disc no less than 30 degrees open. For best results, the disc should be between 30 and 70 degrees open. High pipeline velocities and/or throttling with the disc less than 30 degrees open may result in noise, vibration, cavitation, severe line erosion, and/or loss of control. For details regarding throttling services, contact Victaulic.
• Victaulic recommends limiting the flow velocities for water service to 20 feet/second (6 meters/second). When higher flow velocities are necessary, contact Victaulic. When dealing with flow media other than water, contact Victaulic.
• Lubricated nitrile “T” seat seals are recommended for dry or lubricated gas services.
• When directly connecting an end cap to a Series 761 or 461 Butterfly Valve, use only an end cap with a tapped hole for attaching a pressure relief device. If the valve is opened then closed unknowingly while the end cap is attached, the space between the disc and end cap will be filled and pressurized. A sudden release of energy can occur if the end cap is removed while the space behind it is pressurized. PRESSURE MUST
BE VENTED THROUGH THE TAP BEFORE ATTEMPTING TO REMOVE THE CAP.
DANGER
• When directly connecting an end cap to a butterfly valve, use only an end cap with a tapped hole for attaching a pressure relief device.
• Pressure must be vented through the tap before attempting to remove the cap.
Failure to follow these instructions could result in death or serious personal injury.
VIC-FLANGE® ADAPTER NOTES
• Style 741 Vic-Flange® Adapters can be used on all sizes of Series 761 Butterfly Valves.
• Series 761 Butterfly Valves cannot be connected directly to flanged components with Style 743 Vic-Flange® Adapters. A No. 46 ANSI 300 groove-by-flange adapter is required for this application.
• Style 441 Stainless Steel Vic-Flange® Adapters can be used on all sizes of Series 461 Butterfly Valves.
SYSTEM-RELATED CONSIDERATIONS
• Series 761 and 461 Butterfly Valves and connecting piping must be supported properly to prevent the joints from being subjected to bending loads, shear loads, or any other external loads.
• The maximum allowable corrosion allowance is 0.8inch/2 mm.
• Welding to Series 761 and 461 Butterfly Valves and couplings is not permitted.
PREVENTION OF STAINLESS STEEL PRODUCT CONTAMINATION
These recommendations are provided as a general guideline to help prevent surface contamination of stainless steel products.
Handling and Storage
1. Stainless steel products should be handled only with non-
contaminating apparatus (i.e. nylon straps or apparatus protected with a non-contaminating buffer material).
2. If carbon steel straps are used, a buffer material must be placed between the strap and the stainless steel product. Common non­contaminating buffer materials include wood, cardboard, paper, canvas, and other stainless steel material.
3. Stainless steel products must be stocked on non-contaminating racks or skids.
4. Stainless steel products must be stocked in an area separate from iron or carbon steel products.
5. Do no climb on or stand on stainless steel products.
6. In storage areas where salt is present in the air, stainless steel
products must be covered with a plastic tarp.
Shipping
1. Stainless steel products must be shipped with new, non-
contaminating and non-damaging packing materials.
2. If markings are required directly on stainless steel products, the marking must have a water-soluble chloride content less than 50 parts per million (ppm). The chloride content must be measured upon drying of the marking.
3. Identification tags and connectors, if required, must be constructed from non-contaminating materials.
4. Stainless steel products must be shipped separately from iron or carbon steel products. If stainless steel and/or iron or carbon steel products must be shipped together, care must be taken to separate the dissimilar materials completely by using a non­contaminating buffer.
WARNING
• The system designer is responsible for verifying suitability of stainless steel materials with the intended fluid media.
• The effect of chemical composition, pH level, operating temperature, chloride level, oxygen level, and flow rate on stainless steel materials must be evaluated to confirm system life will be acceptable for the intended service.
Failure to follow these instructions could cause product failure, resulting in serious personal injury and property damage.

STEM SEAL REPLACEMENT FOR 2 – 12-INCH/60.3 – 323.9-MM VALVES
WARNING
• Read and understand all instructions before attempting to replace the stem seals.
Failure to follow all instructions could result in serious personal injury and/or property damage.
WARNING
• THE PUMP MUST BE SHUT OFF to prevent flow from passing through the valve during the following procedures.
Failure to follow this instruction could cause product failure, resulting in serious personal injury and/or property damage.
4. Using retaining-ring pliers or a similar device, remove the retaining ring from around the stem assembly, as shown above. If the retaining ring is bent from its original shape, replace it with a new, Victaulic-supplied retaining ring.
NOTICE
• THE STEM SEAL REPLACEMENT PROCEDURE SHOULD BE COMPLETED ONLY IF LEAKAGE IS OCCURRING FROM THE STEM.
• Make sure the correct stem seal kit was ordered by verifying the o-ring material.
• O-rings for all valve sizes (12 total) are included with the kit. However, only four o-rings are required to repair one valve. Make sure the correct size o-rings are used for the stem seal replacement procedure. Discard any unused o-rings.
1. Removal of the handle assembly or gear operator can be performed without removing the valve from the piping system. THE PUMP MUST BE SHUT OFF to prevent flow from passing through the valve during removal of the handle assembly or gear operator.
2. To remove the handle assembly: Refer to the appropriate handle removal section in this manual.
3. To remove the gear operator: Note the current orientation of the gear operator before proceeding with the following steps. AS A REFERENCE FOR GEAR OPERATOR RE-INSTALLATION: Place a mark on the gear operator, the stem, and the valve body mounting flange with a permanent marker or paint pen.
3a. Place the valve disc in the OPEN position by turning the
handwheel of the gear operator until the pointer is pointing toward the OPEN position.
3b. Remove the four existing hex-head screws and lock washers
that attach the gear operator to the valve body mounting flange. NOTE: These hex-head screws and lock washers are required for re-installation.
3c. Pull straight upward to remove the gear operator and existing drive
bushing from the valve body mounting flange. These items are required for re-installation. DO NOT REMOVE OR ROTATE THE
STEM.
3d. Remove any debris from the valve body mounting flange.
5. Remove the stem assembly from the disc/valve body. Be careful not to damage the flats of the drive hub during removal.
6. Remove the seal cartridge from the stem.

11. Install two new o-rings onto the seal cartridge, as shown above.
7. Using an o-ring pick or a similar device, remove the two internal and two external o-rings from the seal cartridge.
8. Clean the stem and the interior and exterior surfaces of the seal cartridge. Check the surfaces of the stem and seal cartridge for burrs and sharp edges. File any burrs and sharp edges to prevent o-rings from being cut during re-assembly.
9. Lubricate the seal cartridge and o-rings with Vic-Lube™ or another compatible material, such as silicone.
CAUTION
• Use a compatible lubricant to prevent the o-rings from pinching/ tearing during installation.
Failure to follow this instruction could result in valve leakage through the stem.
12. Insert the stem into the seal cartridge.
13. Insert the stem assembly into the valve body/disc. Make sure the rectangular end of the disc aligns with the stem. NOTE: The seal cartridge must seat fully in the valve body.
14. Using retaining-ring pliers or a similar device, install the retaining ring over the stem assembly. Make sure the retaining ring fully seats in the recess in the valve body.
15. Re-install the handle assembly or gear operator onto the valve.
10. Install two new o-rings into the seal cartridge, as shown above.
