NIBCO High Performance Butterfly Valves

Series 6822 and 7822

Statements:

NIBCO High Performance Butterfly Valves, Series 6822 and 7822, have been designed and manufactured for fluid control handling in
suitable mechanical systems. It is important to follow the instructions below to assure proper valve installation and safe trouble-free
operation. Failure to follow these instructions may result in reduced valve performance and may cause loss of manufacturer’s
warranty.

1. Application:

1.1 The selection of the valve design and materials of construction as related to the specific service application is the sole
responsibility of the end user.

1.2 All NIBCO HPBFVs have an Identification Plate attached to the perimeter of the valve top flange. Important information
including valve size, class, materials of construction, and pressure/temperature ratings are shown.

1.3 Review corrosive effects of the media to be used in the valve and assure it is compatible with the valve materials of
construction.

1.4 Do not install the valve where the pressure/temperature ratings can be exceeded. As temperature increases, the safe
working pressure decreases. The pressure/temperature ratings are based on API Standard 609 and can be found in the
appropriate NIBCO Butterfly Valve catalog.

1.5 Valves should be regularly maintained; reference Section 7. Valves used in services where erosion or other detrimental
situations can occur should be inspected on a regular basis.

2. Storage:

2.1 Valves are shipped in the closed position with flange covers to protect the sealing surfaces and internal valve parts. These
covers should remain on the valve until actual installation into piping.

2.2 The valves must be stored in a dry environment, protected from temperature extremes and possibility of damage. The
valve body is made from carbon steel and rust can appear on inside surfaces, this will not affect valve performance.
Special care should be taken to prevent damage to the disc edge and sealing surfaces.

3. Installation:

3.1 Inspect the piping and remove all dirt, welding slag, rust, and scale from the piping and flange faces. It is advisable to
install a strainer upstream of the valve to prevent contamination from entering the valve. It is very important for long
trouble-free service to keep the valve free of all contamination that may damage the seal surfaces.

3.2 Remove the protective covers from valve faces and carefully check the valve for any damage that may have occurred
during shipping and handling.

3.3 Fully open the valve and verify that sufficient diametrical clearance is available for the valve disc to extend into both
mating pipe flanges and piping.

3.4 Cycle the valve from full open to full closed positions checking to assure the operator stops are set properly. Stops must
be properly set before the valve is installed into the piping. See Section 4 for proper stop adjustment procedure.

Installation, Operation and Maintenance Instructions

NIBCO 6822 and 7822 Series High Performance Butterfly Valves

3.5 Fully close the valve before installation into piping to prevent damage to disc.

3.6 Determine valve orientation. The valve can be installed in any position or direction; however it is preferred to install the

valve so flow direction matches the direction arrow cast in valve body and with the stem in the horizontal (±30°) position.
This allows better protection for the seat from particles flowing in the media and from sediment build-up at stem base
giving optimal valve service life. This is very important for steam service applications due to the high travel velocities.

3.7 Always check to assure seat retainer screws are securely tightened. Refer to Section 7.19 for procedure and proper torque
specifications.

3.8 New flange gaskets are required between valve and flanges. Valves are designed to work with 1/16” thick fiber and
metallic wound gaskets. Gaskets are customer supplied.

3.9 Align gasket with valve face and pipe flanges. Install proper size cap screws (bolts) thru the flange and loosely tighten
into threaded valve mounting lugs. See Section 5 for proper cap screw sizing.

3.10 Fully open and close the valve to verify proper operation and that the disc moves freely.

3.11 First, snug all caps screws using the “Cross-over” diagonal method. Second, evenly tighten all screws using the “cross-

over” diagonal method to the proper torque for the Grade Designation of cap screw being used. Do not over tighten cap
screws.

3.12 Again fully open and close the valve to verify proper operation and free disc movement.

3.13 While NIBCO HPBFVs are rated for dead-end service, NIBCO recommends that a down-stream flange be used.

4. Stop Adjustment:

4.1 HPBFVs can be actuated by a manual lever, a manual gear operator, an electric actuator, or a pneumatic actuator. No

matter what style of actuation is used, it is critical that the actuator CLOSED travel limit stop is properly set to
match valve disc/seat orientation for proper seal. The OPEN stop adjustment is not critical; ±5° travel is adequate.

4.2 The CLOSED actuator stop should be set before the valve is installed into piping so you can visually see that the disc is

centered in the seat (disc front face is parallel with seat retainer face). Note that the valve has an “over-travel” stop at
the disc edge. This “over-travel” stop is only to keep the disc from rotating too far thru the seat. When the disc is properly
centered in the seat, the disc edge usually does not contact the “over-travel” stop.

4.3 There are several different manufactures of gear operators, electric and pneumatic actuators. While the adjustment

procedure is not exactly the same for all manufacturers, they are all very similar to procedures described below.

Manual Lever Adjustment

4.4 Move the lever handle into the closed position and allow trigger to securely latch in the last notch of the throttle plate.

Visually inspect the disc to assure it is centered in the seat. If not, slightly loosen the (2) cap screws that hold the throttle
plate to the top flange of valve. With the trigger securely latched in last notch, rotate manual lever (and throttle plate)
until disc is centered in seat. There is enough clearance in throttle plate mounting holes to allow for adjustment. Securely
tighten throttle plate cap screws. Cycle valve from CLOSED position to OPEN position, then back to CLOSED. Verify disc
is centered in seat when CLOSED. Adjustment of OPEN stop in not necessary, as it will automatically be set.

6. Operation:

6.1 The valve can be actuated by a manual lever, a manual gear operator, an electric actuator, or a pneumatic actuator. Turning
the valve (as viewed from top) clockwise closes the valve; counter-clockwise opens the valve.

6.2 Due to the double offset design of HPBFVs, the differential pressure over the disc can cause sufficient torque to open the
valve spontaneously. For this reason, it is important not to remove lever or actuator from a valve that is or will be pressurized.

6.3 Lever operated valves should always be locked securely in desired throttle plate notch to prevent unexpected disc movement.

7. Maintenance:

7.1 Typical maintenance consists of periodic inspection and exercising (cycling) of the valve to assure proper function.

7.2 Fluid leakage at weep hole near top of valve neck below flange is an indication that the stem packing needs tightened.

Evenly tighten both nuts (8) below valve top flange ¼ turn each until leakage stops. It is important to adjust nuts evenly
and not to over-tighten or premature stem packing wear will occur.

7.3 If repair parts or service information is required, please locate valve Identification Plate (23) and supply following information:

• Valve Figure Number

• Valve Size

• Valve Class

• Manufacture Date Year

• Valve Serial Number

• Type of Actuator

7.4 Three individual repair kits are available for each size valve.

• Stem seal kit including Packing Set (5), Packing Retainer (6), and Lower Seal (19).

• Standard RPTFE Seat (13) 15% glass reinforced PTFE

• Special 25% carbon filled Seat (13) for severe steam service.

7.5 Some individual component parts can be ordered. Contact NIBCO for availability.

Precautions Prior to Valve Removal from Piping or Repair

7.6 Turn off supply pressure to piping in which valve is located. Lock-out & Tag-out per established safety procedure.

7.7 Identify media in piping and determine how to safely drain piping. Use proper personal protection clothing

and supplies as needed.

Removal of Valve from Piping

7.8 Check to confirm piping has been depressurized and drained.

7.9 Actuate valve until in full CLOSED Position.

7.10 Attach appropriate lifting strap or sling to valve neck. Attach other end of strap or sling to secure point capable of

supporting valve weight.

7.11 Disconnect any supply lines (air and electric) to actuator if applicable. Lock-out & Tag-out per established safety procedure.

7.12 Unloosen and remove all cap screws from mating pipe flanges.

7.13 Remove valve from between flanges. Remove old gaskets and clean piping flange seal surfaces of old gasket residue.

7.14 Note that any time the valve is removed from between flanges, it if necessary to re-torque seat retainer cap screws (10).
