Description

Honeywell VFF2KV1Y2EM Butterfly Valves Flanged Butterfly Valve with Resiliant Seat 2-Way Non-Spring Return Normally Closed 5″

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 chilledwater-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 nonactuatedmodels 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

• Sizes from 2 to 20 inches with ANSI Class 125/150 lug pipe connections.
