Electric Linear Travel Modulating Valve Actuators

intelligent valve actuator & easy to contral

1.GENERAL DESCRIPTION

Electric Linear Travel Modulating Actuator is a new member of series SND. These products are suitable for the closed loop control system of industry process and able to carry out reliable and accurate control on modulating valves. They are used extensively power plants, metallurgical industry, sewage disposal and ventilation.

The general performance of these products is conformed to the requirements of Standard JB/T 8219- Electrical Actuators for Industrial-process Measurement and Control System. These actuators are light in weight, small in size, easy to set and provided with accurate control and long time for service life. These actuators are provided with many protecting functions, such as interlocking in opening and closing, protection for over torque, and travel limit, etc.
