We have been producing the ACHEM C series specific pneumatic actuators for more than 20 years. There are two kinds of special type of actuator made by us, one is large stroke actuator, the other is three-position actuator. These actuators can meet the special requirements of various valves and automatic rotary devices. The three-position actuator can not only provide perfect control scheme for three-way or four-way valve, but also effectively solve the problem of water hammer in industrial pipeline.

1. Large stroke actuator

1.1 An actuator with a rotation stroke of more than 120°is called a large stroke actuator. Based on our standard stroke (90°) actuator, as long as we are equipped with large stroke pistons and body and specially designed cam, the actuator will be able to perform the work of a large stroke. This stroke can be determined according to the needs of the customer, such as 120° , 130°, 180° , 240° and so on.
1.2 The size of the large stroke actuator is the same as that of the standard actuator, except for the length which are shown in tabel below.

Note that the top of the large stroke actuator at C125 and above size is equipped with two mounting rings.

1.3 The output torque is the same as that of the standard actuator of 90°. Note that our C series large stroke actuator is only available for double acting now.
