Johnson Controls V-3766, V-3966, V-4332 Catalog Page
Brass Pneumatic Flare Valves
Code No. LIT-1924115
Issued January 2, 2014
V-3766, V-3966, and V-4332 Brass Pneumatic Flare Valves, 1/2 in. Two-Way and
Three-Way
Description
The 1/2 in. flared valve line accurately
regulates the flow of hot or cold water in small
HVAC terminal units. These 1/2 in. valves are
available with a factory-installed V-3000-1
exposed type pneumatic actuator; enclosed
actuators (V-3000-2) are also available (order
separately). This valve style is available for
field mounting the VA-805x Series electric
actuators or with a factory-coupled
VA-805x Series electric actuator.
Refer to the Flare Valves 1/2 in. T wo-Way and
Three-Way Product Bulletin (LIT-977175) for
important product application information.
Features
• 1/2 in. OD SAE 45 flare connections do not
require solder installation with copper
tubing; provides easy removal for
maintenance
• standard Johnson Controls®
non-adjustable ring pack packings provide
proven reliability and long life
• body rated 400 psig static pressure does
not restrict building location
• every valve tested for tight initial and
long-term shutoff; ensures occupant
comfort and energy conservation
• factory-assembled valves available with
pneumatic or electric actuators; install
quickly and easily, minimizing job site time
