Honeywell VFF1, VFF2, VFF3, VFF6 Data Sheet

VFF1, VFF2, VFF3, VFF6 Resilient Seat Butterfly Valves with Flanged Connections

PRODUCT DATA

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.

FEATURES
All Models
• Sizes from 2 to 20 inches with ANSI Class 125/150 lug pipe
connections.
• 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.
• Bubble-tight seat leakage at rated close-off.
• Close-off rating of 175 psid in sizes 2 in. to 12 in. with full-
cut disks.
• Close-off rating of 150 psid in sizes 14 in. to 20 in. with full-
cut disks.
• 250 psi end-of-line close-off pressure rating with non-
automated 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.
