Honeywell VFF20000/M

What is the Honeywell VFF20000/M?

VFF2 2-way resilient seated, flanged butterfly valves 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. 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. They are also available as non-actuated models with either lever or gear manual operators for use as shut-off and balancing valves. Spring return actuators are available in normally closed 2-way configurations. Features & Benefits:

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

Anti-condensate heaters standard with NEMA 4X and NEMA 4 actuators
