Butterfly Valves
VFF2 Resilient Seated 2-Way Butterfly Valve
VFF2 resilient seated 2-way butterfly valves provide control for HVAC systems, including chilled water, hot water, cooling tower water, and thermal storage systems.
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:- Bi-directional flow
