4inch Butterfly Valve, with VB110M-023 Electric Actuator, 4-20ma Input
N501S Lug butterfly valves. Epoxy
coated ductile iron lug body. ISO 5211
direct mounting pad/square stem. Food
grade EPDM resilient seat -30°F to 250°F
at 1PSI. API609 face to face flange. SS
disc. Floating dual shaft disc design.
Pressure rating: 250 psi water (40°F to
80°F). MSS SP 67 compliant. No pins in
disc prevent potential leak points. NSF
certified for drinking water service
(EPDM seats only). Dead end service to
100 psi. With VB110M-023 modulating
electric actuator 100-240V AC with 4-
20mA signal, metal housing, Nema 4, UL
Certified, visual dome position
indicator, auxiliary switches, heaters,
overload protection, hand wheel manual
override with power switch, 1/2"
conduit connection. Actuator sized for 250PSI working pressure.
Note: BFV are not good for fine controls. Actuator point of resolution 64,
which means it will move every 0.25mA.
