Spring return operation function (standard rotation) TOP view:
● Air supplied to Port 2 forces the pistons apart and toward the actuator end caps, compressing the springs with the exhaust air existing at Port 4, a counter clockwise rotation is achieved.
● On loss of air pressure (air or electric failure) at Port 2 allows the springs to force the pistons together with the exhaust air exiting at Port 2, a clockwise rotation is achieved.
AT Spring ReturnAs an important implementing agency in the industrial automation control system, the remote centralized control can meet the requirements of computer program control. Nowadays, it is widely used in petrochemical industry, gas equipment, nuclear industry, power equipment, environmental water treatment, HVAC, steel metallurgy, Textile, printing and dyeing, paper and other industries are widely used, but also the construction of national defense, science and technology construction of the product of choice for the construction of the building materials, construction machinery, machinery and equipment, machinery and equipment.
