Zhejiang Jimai Auto-tech Co., Ltd. has recently developed a pneumatic actuator with a range of 0-180 degrees in order to fulfill a specific valve request. It is capable of achieving a full range of rotation of 180 degrees for the shaft,which can be used in 180 degree rotation valves. There is a smooth and rapid rotation as well. Furthermore, it is equipped with two modes of operation, namely double-acting and spring return. Customer can choose normally open or normally close type for spring return actuator. The output torque of a 0-180 degree pneumatic actuator is identical to that of a rotary pneumatic actuator when the air pressure that is given to the actuator is the same. The 0-180 degree pneumatic actuator has a significantly longer length than the rotary pneumatic actuator, which is the only difference between these two models. For the purpose of providing services to the valve industry, Zhejiang Jimai Auto-tech Co., Ltd. will continue to develop and improve its products.
