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 two and three-way forged brass valves is factory or field mounted to Johnson Controls VA9104 and VA9300 Series Non-Spring Return and VA9203 and VA9208 Series Spring Return Electric Actuators for on/off, floating, or proportional control. For sweat and press end connection valves supplied with an actuator, the actuator is not mounted to the valve to allow access to the end connections.
