Today, by Wuxi Xinming automatic control valve industry Co., Ltd. for you to introduce in detail 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 mechanism that is driven by an external power source to produce a specific motion that controls 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 motion, thereby controlling the valve. In a common pneumatic actuator, a diaphragm actuator pumps air into a hollow housing, where the pressure that occurs acts on a flexible rubber diaphragm to deflect it from its original orientation. The diaphragm connected to the valve stem moves up or down to condition the valve disc and control the fluid flow. Pneumatic actuators typically produce linear motion, but can also be used to produce rotational 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. Electric actuators use AC or DC powered servo motors to move the valve to the desired orientation. Electric actuators are capable of linear or rotary motion. The strengths and uses of pneumatic actuators Pneumatic actuators are capable of generating an upper limit of closing force in all actuator types. Some pneumatic actuators have an additional pressure limit of 250 psi, which can generate up to 40,000 lb of force. With this actuator, a relatively fast closing speed of 2 m/s can also be reached. Through the system of conditioning pressure relief valve or flow conditioner, the speed and force of the actuator can be easily fine-tuned. 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, short ignition source and high reliability, making them ideal for use in internal combustion engines, pumps, ventilation systems, and in flammable or flammable environments.
