VG1000 Series Two-Way, Spring-Return,
Stainless Steel Ball and Stem Ball Valve
Assemblies with End Switches
VG1000 Series Two-Way, Stainless Steel Trim, NPT End Connections Ball Valves
with Spring-Return Electric Actuators with Switches
Description
VG1000 Series Ball Valves are designed to
regulate the flow of hot or chilled water and, for
some models, low-pressure steam in
response to the demand of a controller in
HVAC systems. Available in sizes 1/2 through
2 in. (DN15 through DN50), this family of twoand three-way forged brass valves is factory
or field mounted to Johnson Controls®
VA9104, M9106, M9109, and M9100 Series
Non-Spring-Return and VA9203 and
VA9208 Series Spring-Return Electric
Actuators for on/off, floating, or proportional
control.
Refer to the VG1000 Series Forged Brass Ball Valves Product Bulletin (LIT-977132) for
important product application information.

• 500:1 Rangeability — provides accurate
control under all load conditions.
• Maintenance-Free Design — performs
without failure in excess of 200,000 full
stroke cycles in iron-oxide contaminated
water.
Repair Information
If the VG1000 Series Ball Valve fails to
operate within its specifications, replace the
valve body, actuator, or entire assembly. For
replacement parts, contact the nearest
Johnson Controls representative.

1. Proper water treatment is recommended; refer to the VDI 2035 Guideline.
2. Rangeability is defined as the ratio of maximum controllable flow to minimum controllable flow.
3. In steam applications, install the valve with the stem horizontal to the piping and wrap the valve and piping with insulation.
