Butterfly Valves

Resilient Seat Flanged Butterfly Valve

VFF1/VFF2 two-way and VFF3/VFF6 three-way flanged, resilient seated butterfly valve assemblies provide compact, 2-position and modulating control of hot water and chilled water-glycol solutions in HVAC systems. Valve sizes range from 2 to 20 inches.

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. Valve sizes range from 2 to 20 inches. Valves with full cut disks provide up to 175 psi close-off.

These valve assemblies are shipped with factory-mounted electric or pneumatic actuators with a variety of control signal inputs. Two-way bodies are also available as non-actuated models with either lever or gear manual operators for use as shutoff and balancing valves. Spring return actuators are available in normally open or normally closed two-way configurations.

Three-way valve assemblies consist of a pair of two-way valve bodies with a common actuator mounted on a standard, iron pipe tee. Either A-B-AB porting or A-AB-B porting is available. The A-port is factory-set to the normally closed position, but the linkage assemblies are field adjustable to seven other configurations.

Features & Benefits:
  • Bi-directional flow; modified equal percentages flow characteristic
  • 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, UV, 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 from 2 to 12 inches with full cut disks; 150 psid in sizes from 14 to 20 inches 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 to 10V DC), modulating/floating spring return
  • Available with three, factory-installed high pressure electro-pneumatic interfaces in spring return and bi-directional configurations: 24V AC solenoid, 120V AC solenoid, and modulating input, available position status indicator switches
