Description
VG2000 Series Valve
VG2000 Series Cast Iron Flanged Globe Valves are designed primarily
to regulate the flow of water and steam in response to the demand of a
controller.
Refer to the VG2000 Series Cast Iron Flanged Globe Valve Product Bulletin (LIT-977133) for important product application information.
MP8000 Series Actuators
MP8000 Series Pneumatic Actuators are designed to accurately
position hot-water, chilled-water, and steam-control valves in response
to a pneumatic signal from a controller.
Refer to the MP8000 Series Pneumatic Valve Actuators Product Bulletin (LIT-977257) for important product application information.
