Electric Butterfly Valve Actuated Wafer type butterfly valves,Control style On-Off, DN50 DN65 DN80 black
OVERVIEW
Electric Actuated Butterfly Valves
electric actuators rotate an output drive to open and close butterfly valves. Electric actuators provide a reliable and economical method of operating these valves from a remote location. For modulating valve applications, an electric actuator with EPS positioning can control the valve flow with a 4-20mA command signal.
Butterfly Valve, Wafer Type, Slim-Seal design, maintenance free shutoff. This butterfly valves excess other conventional valves such as gate valve and globe valves in all aspects, especially in terms of light weight, less number of component, no flange gaskets required and economical operation and maintenance costs.
We have a full range of valve electric actuators, e.g., multi-turn electric actuators, part-turn electric actuators, quarter-turn electric actuator, and linear electric actuators, which are used in a variety of valves and dampers, such as gate valves, globe valves, ball valves, butterfly valves, plug valves, globe control valves, and diaphragm valves, so we have lots of valve partners in china, we can choose the suitable valves for you, even for valve selection if you are required!
