Honeywell VFF1, VFF2, VFF3, VFF6 Data Sheet

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

PRODUCT DATA

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.

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.

• Non-automated valves available with choice of manual
lever or gear operators.

Three-Way Valve Assemblies (VFF3/VFF6)

• Mixing or diverting control.
