Electronic type electric hard sealing double eccentric butterfly valves
features:
DYH971H electric hard sealing butterfly valve is made from hard sealing butterfly valve and NA type full electronic type electric actuators. Butterfly valve adopts special design disc, seat eccentric structure, makes the valve have a good sealing performance, reducing the seal closed wear smaller, litter friction and long service life. Stainless steel seat ring is suitable for the high temperature process flow. NA type electric actuators use built-in electronic controller module integration, with no other servo amplifiers. The actuator is with high precision, compact structure, reliable action, and can provide enough torque to reach the position. When power off, stir cluth handle, can through the safety, labor-saving handwheel to manual operation, when power on, stir cluth handle, it will automatic recovery. Built-in valve position feedback device can achieve the valve position signal transmission and remote control.
