Today, by Wuxi Xinming automatic control valve industry Co., Ltd. for you to introduce what are the advantages of pneumatic actuators? Let's talk about the advantages of pneumatic actuators before answering. What is an actuator? Valve actuators are automated mechanical devices that regulate the orientation of various types of valves. The actuator itself is a tissue that is driven by an external power source to produce a specific movement that manipulates the orientation of the valve. The motion of the actuator can be linear (horizontal or vertical motion) or rotational (rotation around a fixed axis). There are several different types of valve actuators. However, most actuators fall into two categories: electric actuators or pneumatic actuators. The primary difference between these two types of actuators is the primary driving force applied in their operation. Pneumatic actuator Pneumatic actuators use air (or other gas) pressure as the primary power to generate movement, and then operate the valve. In the most common pneumatic actuator, a diaphragm actuator pumps air into a hollow housing where the pressure that occurs acts on a flexible rubber diaphragm to cause it to violate its original orientation. The barrier attached to the valve stem moves up or down to condition the valve disc and manipulate fluid flow. Pneumatic actuators typically produce linear motion, but can also be used to produce rotary motion. Electric actuator On the other hand, electric actuators use electricity as the primary power to drive the actuator movement. Electric actuators are divided into two categories: electromagnetic actuators or motor-driven actuators. In a solenoid-driven actuator, current flows through a coil to generate a magnetic field that moves the metal valve stem to condition the orientation of the valve disc. The electric actuator uses a communication or DC powered servo motor to move the valve to the desired position. Electric actuators are capable of linear or rotary motion. The strengths and usefulness of pneumatic actuators Pneumatic actuators are capable of generating the largest closing forces of all actuator types. Some pneumatic actuators are rated for a maximum pressure of 250 psi and can generate a maximum force of 40,000 lb. With this actuator, a relatively fast closing speed of 2 m/s can also be reached. The speed and force of the actuator can be easily fine-tuned by a system of conditioning pressure relief valves or flow conditioners. Another primary advantage of pneumatic actuators is their low unit cost. Pneumatic cylinders are cheap and can be easily upgraded to larger diameters. Large air compressors are also very efficient and economical for powering large pneumatic equipment. These actuators are known for their clean operation, lack of ignition sources and high reliability, making them the aspiring choice for internal combustion engines, pumps, ventilation systems, and applications in flammable or flammable environments. The above is all about the advantages of pneumatic actuators specifically introduced by Wuxi Xinming automatic control valve industry co., ltd. if you have any questions about pneumatic actuators, please feel free to call for advice and wait for your cooperation.
