Angle Butterfly Linear Valve Actuator / Spring Electric Cylinder Actuator

Cylinder Actuator

AoTu-C1 Pneumatic cylinder actuators are well suited to those applications beyond the usual field of the pneumatic diaphragm type actuators. They can be feed with high air pressure to give high thrusts; they have no limit in stroke, their thrust/travel characteristic is quite linear, their performance shall not be reduced for low temperature service.

In spite of such advantages, cylinders require accurate manufacturing and careful finishing which can bring up costs, together with the need for a positioner because of the high dead-band of piston not suited to a good throttling operation.

Cylinder actuators AoTu-C1 series can be fitted on all types of global, angle and butterfly calves manufactured by OTEKER.

Single-action actuators consist of a spring-opposed piston actuated by air pressure. They offer the advantages of a simple fail-safe action(when air pressure fails, the compressed spring load overcomes the pressure load and moves the stem to open or to close the valve port according to required fail-safe action), and of a good stability when the load on the plug varies.

The series is composed by 2 actuator sizes:C450 and C600.

Social Commitment

For the past 100 years, chemistry and material science have brought people great convenience in almost all aspects of human's daily life. However, severe environment contamination has also been caused as by-product by the mushroom industrial development, jeopardizing water, soil, air quality. Energy shortage and environment protection have become a severe issue globally.

Being a new-born innovative company, UniNano is dedicated to lowering carbon emission during manufacturing process and offering energy conservation solution. To set an energy-saving and environmental example in developing series of thermal insulation materials, UniNano will spare no efforts to provide our customers continuously with efficient, effective and eco-friendly solutions.
