These are 360° turn gear actuators, suitable for gate valve, globe valve, T-Cock ball valves, butterfly valves, and plug valves etc. The housing is precisely cast, with fresh pattern and nice appearance. Transmit by spur gear, deep groove ball bearing and thrustl bearing combination makes the transmission more flexible and efficient. The connecting part of gear and valve stem can be uni-body or seperated optionally. The connectting flange adapts to ISO.5210 makes it easy
