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