V-3766, V-3966, and V-4332

Brass Pneumatic Flare Valves 1/2-Inch 2-Way and 3-Way

Code No. LIT-1924115

Issued August 24, 2011

Brass Pneumatic Flare

Valves

Description

The 1/2 in. flared valve line accurately

regulates the flow of hot or cold water in small

Heating, Ventilating, and Air Conditioning

(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. For

important product application information,

refer to the Flare Valves 1/2-Inch 2-Way and 3-

Way Product Bulletin (LIT-977175).

Features

• 1/2 in. OD SAE 45 flare connections do not

require solder installation with copper

tubing; provide 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
