• Bi-directional flow.
• Modified equal percentages flow characteristic.
• Extended neck for 2 inches of pipe insulation.
• Nylon 11-coated, cast iron disks for corrosion resistance, reduced friction and use of lower-torque actuators with larger valves body sizes.
• Cast iron valve body polyester-coated for weather, chemical, ultra-violet, abrasion, and impact protection.
• Stainless steel valve stem with close-tolerance internal double-D disk connection with no points for corrosion access.
• Peroxide-cured EPDM resilient valve seat doubles as flange gasket.

APPLICATION

The VFF1/VFF2 two-way and VFF3/VFF6 three-way flanged, resilient-seated butterfly valve assemblies provide compact, two-position and modulating control of hot water and chilled water-glycol solutions in heating, ventilating, and air conditioning (HVAC) systems. Valves sizes range from 2 to 20 inches. Valves with full-cut disks provide up to 175 psi close­off.
These valve assemblies are shipped with factory-mounted electric or pneumatic actuators with a variety of control signal inputs. VFF2 two-way bodies are also available as non­actuated models with either lever or gear manual operators for use as shut-off and balancing valves.
Spring-return actuators are available in normally open (VFF1) or normally closed (VFF2) two-way configurations.
Three-way valve assemblies consist of a pair of 2-way valve bodies with a common actuator mounted on a standard, iron pipe Tee. Either A-B-AB porting (VFF3) or A-AB-B porting (VFF6) is available. The A-port is factory-set to the normally closed position, but the linkage assemblies are field­adjustable to seven other configurations.
• Bubble-tight seat leakage at rated close-off.
• Close-off rating of 175 psid in sizes 2 in. to 12 in. with full­cut disks.
• Close-off rating of 150 psid in sizes 14 in. to 20 in. with full­cut disks.
• 250 psi end-of-line close-off pressure rating with non­automated valves.
• 50 psid close-off rating, lower operating torque with undercut disks.
• ISO 5211 actuator mounting flange.
• Available with four, factory-installed electric actuation interfaces in 24V and 120V power: 2-position spring return, Floating (“tri-state”), Modulating (2-10 Vdc), Modulating/ Floating Spring Return.
• Actuators available in NEMA 2 (general purpose), NEMA 4X (watertight/corrosion-resistant), and NEMA 4 (watertight) enclosures.
• Anti-condensate heaters standard with NEMA 4X and NEMA 4 actuators.
• Declutchable override handwheel standard with NEMA 4X actuators.
• Non-declutchable, override handwheel standard with NEMA 4 actuators.

INSTALLATION

When Installing this Product:

1. Read these instructions carefully. Failure to follow them
could damage the product or cause a hazardous condi­tion.
2. Check ratings given in instructions and on the product to ensure the product is suitable for your application.
3. Observe and follow all national, state/provincial, local plumbing, fire and electrical codes.
4. Installers must be licensed pipe fitters, electricians and/ or service technicians. This publication requires all installers to be trained and experienced in their trades.
5. After installation is complete, check out product opera­tion as provided in these instructions.
6. Full close-off ratings for automated valves apply only when valve is mounted between two flanges. Valve close-off is de-rated when installed on one flange in end­of-line service due to lack of compression on seat seal. Close-off rating of 2 to 12 inch full cut valves mounted to a single flange is 75 psi. Close-off rating of 14 to 20 inch full cut valves mounted to a single flange is 50 psi.

Preparation

Safety
Honeywell assumes no responsibility for damages or injuries resulting from non-compliance with installation instructions or standard good practice when mounting, operating, or maintaining the valves, even if not explicitly mentioned in the installation instructions.
Equipment Damage Hazard:
• Foreign particles like dirt and metal chips can damage valve seals. For trouble-free operation of the product, good installation practice must include initial system flushing, and chemical water treatment. The presence of excessive rust (Fe
) in the system may void Warranty.
2O3
• Clean the lines upstream of particles larger than 1/16 inch (1 mm) diameter (welding slag, pipe scale, sand and other suspended particulate). Use of a 50 micron (or finer) system side-stream filter is suggested. Remove all filters before flushing. Use of 20 mesh strainers in the system is recommended.
• Follow boiler or chiller manufacturer’s recommendations for water treatment such as rust inhibitors, acidity, etc.
• Rapid increases in pH levels can create excessive quantities of magnetite (Fe and other components.
• Do not use boiler additives, solder flux and wetted materials which are petroleum-based or contain mineral oil, hydrocarbons, or ethylene glycol acetate. These may cause the seat to swell, impairing operation. If treating system with azole-based compounds, system must be thoroughly flushed before filling, or resilient seat may be damaged. Compounds which can be used, with minimum 50% water dilution, are diethylene glycol, ethylene glycol, and propylene glycol (antifreeze solutions).
• If installing these valves in an addition to, or retrofitting and existing building, do not assume that the fluid in the existing piping meets these criteria for water quality or treatment.

Valve Installation

Location
Select a location where the valve and actuator will be accessible, once installed. Allow sufficient space for servicing the valve and actuator. Clearance for valve installation is dependent on actuator size and the valve pipe size. Refer to Figures 1 to 6 for valve body and actuator dimensions.
1. Clean the lines upstream of the valve to remove particles larger than 1/16 inch (1 mm) diameter (welding slag, pipe scale, metal filings, and other contaminants) to prevent damaging or obstructing disk operation.
2. Air should be eliminated from the system so that valves remain full of fluid during operation.
3. To prevent interference with disk operation, a butterfly valve should be installed at least 6 pipe diameters away from other pipe line elements. Where this is impractical, care must be taken to ensure free operation of the disk to prevent damage to moving parts and actuators.
4. Proceed with installation once the system specifics (expansion/contraction of the system and its medium as well as operating pressures) are within tolerances.
5. Valve may be installed with actuator(s) mounted, if pre­ferred.
Mounting 2-way Valves
1. Before installing the valve, rotate the valve stem manu-
ally to make sure that the valve stem operates freely. Impaired stem operation can indicate that the stem was bent by rough handling. This condition may require replacing the valve.
2. Protect the stem from damage due to bending or scratching.
3. For horizontal piping, install the valve so the actuator is in any position between vertical and horizontal, but pref­erably above the valve. Do not install the valve with the stem below horizontal or upside down unless splash­proof or waterproof actuators are used. For vertical pip­ing, the actuator can be mounted in any orientation. See Fig. 15.
Fig. 15. Butterfly valve orientations for Honeywell direct
coupled actuators (DCA's)
4. Hoist valve by its body or neck only, using a nylon sling.
Do not lift by actuator, manual operator, or flange holes. (See Fig. 16 for proper hoisting method.)
63-2661—06 14
VFF1, VFF2, VFF3, VFF6 RESILIENT SEAT BUTTERFLY VALVES WITH FLANGED CONNECTIONS
Fig. 16. Butterfly valve hoisting techniques
5. Mount the valve between aligned pipes. Mounting the
valve on pipes that are not aligned causes leakage at the valve-to-pipe connection and add excess strain to flange bolt lugs. See Fig. 17.
Fig. 18. Flange welding techniques
8. When using welded flanges, loosely assemble valve and
flanges using flange bolts with disk open about 10°. Tack weld flanges to pipes. Remove valve from flanges to pre­vent heat damage and complete flange welding.
9. When flanges have cooled from welding, position the disk in the partially open position, about 10°, keeping the disk at least 3/8 in. (7 mm) inside the body faces. See Fig. 19.
NOTE: The flats of the Double-D valve stem are parallel
to the faces of the disk. Valves are shipped with the disks open slightly to avoid compression set of the resilient seat.
M27029
Fig. 17. Proper flange alignment
6. If installing into an existing system, release system pres-
sure and drain the valve pipe section so the medium (water or glycol solution) does not leak out of the valve body during installation.
7. Iron valves are mechanically compatible with standard ANSI Class 150-flat faced or raised-face steel flanges, or with ANSI Class 125 cast iron flanges. Either neck-weld or slip-on flanges may be used; however, Type C stub- end flanges are not recommended. See Fig. 18.
M27031
Fig. 19. Valve installation disk positions
10. Spread the pipe flanges. Taking care not to damage the
resilient seat gasket, place the body between the flanges, and install all flange bolts. Do NOT use flange
gaskets; the resilient seat serves this purpose.
11. The disk will project into the attached piping. Before
tightening flange bolts, carefully open the disk to the full position to ensure proper alignment and clearance of the disk O.D. with the adjacent pipe I.D. Leave disk in full open position. Snug bolts “hand tight” and then use wrench to tighten bolts an additional quarter to half-turn using a staggered pattern, as with wheel rims of a car. Take care not to over-tighten flange bolts -- compression of rubber increases disk friction.

OPERATION AND CHECKOUT

NOTE: Proper valve close-off depends on the disk clos-
ing fully to compress the resilient rubber seats. Valves are shipped in the slightly open position, used for initial placement, and so that the seat does not ‘set’ and leave a groove from the disk. It is not recommended to leave the disk in the seat for extended periods of time when the valve is not installed. When installed, it is recommended to open the valve periodically. Disk position when actuators are removed from installed valve bodies can be determined by noting the flats of the Dou­ble-D valve stem are parallel to the faces of the disk.

in this publication for reference operate the control system and check valve operation to determine that the valve stem positions the disk smoothly through its full stroke without binding.
Ensure that the actuator selected provides the force to position the valve disk. For electric spring-return actuators, the actuator provides normally closed or normally open operation on electric power or pressure failure, depending on the valve/ actuator combination selected.
General
Spring return actuators return the valve to its normal position (open or closed, depending on the actuator and valve selected) in the event of a power failure. Non-spring return actuators hold the last commanded position.
Pneumatic spring return actuators are factory configured as normally open (VFF1) or normally closed (VFF2). VFF3 and VFF6 3-way valve assemblies are factory configured with the A port normally closed, but the valve linkage may be field­adjusted to one of several other orientations.
Pneumatic actuator torque will vary proportionally to supply air pressure. Depending on torque in excess of valve operating requirements, close-off pressure may vary from published ratings. With air pressure below 80 psi, high pressure bi­directional actuators will lose both seating and unseating torque. Normally open spring return actuators will lose close off torque. Normally closed spring return actuators will lose opening torque. Contact Honeywell for advice on specific, non­standard applications.
Valves with Honeywell spring return direct coupled actuators (DCAs) are shipped with the A port normally closed. This may be converted to normally open by removing the actuator(s), moving the shaft hubs to the other side of the actuator, and re­installing the actuator with the hub in its original orientation. (See Fig. 29.) More than one DCA may be used on the valve to achieve required operating torque.

Once both the mechanical and electrical installations are complete:
1. Cycle the actuator to verify that the direction of rotation suits the control sequence.
2. If the rotation direction is incorrect: a. For 2-position control actuators: Remount actuator
on the bracket.
b. For floating control actuators: Reverse two control
signal wires (CW/CCW).
c. For analog control actuators either:
(1) Reposition reverse/direct acting switch, or (2) Remount actuator on the bracket.
3. If the control scheme requires fail-safe operation, ensure that, upon removal of power, the fail position coincides with the control sequence.
4. If the fail safe position is incorrect, remove and reinstall the actuator in the opposite orientation as follows: a. Loosen the shaft coupling bolt using a 10 mm
wrench.
b. Loosen all other mounting bolts connecting the actu-
ator to the mounting bracket, and set aside. c. Remove the actuator from the valve shaft. d. Move the actuator coupling to the opposite side of
the actuator, as displayed in Fig. 29.
(1) Remove the retainer clip from the shaft coupling
and set it aside for later use.
(2) Remove shaft coupling from one side of the
actuator.
(3) Replace the shaft coupling on the opposite side
of the actuator, aligning it based on the stroke labeling.
(4) Replace the retainer clip on the shaft coupling
using the groove of the coupling.
e. reconnect the actuator to the valve mounting bracket
by replacing the screws previously removed (step b).
f. Tighten the shaft coupling bolt using a 10 mm
wrench.
