What is the definition of a Pic Valves? The term Pic Valves is an acronym for Proportional Integral Controller Valves. They are commonly used in industrial automation systems and are known for their accuracy and reliability. They are used to control the flow of fluids, gases and slurries, and are most often used in automated processes such as temperature control, pressure control, and flow control. Pic valves are made up of two major components: a proportional valve and an integral controller. The proportional valve is responsible for controlling the rate of flow of the fluid or gas, and the integral controller is responsible for maintaining the desired pressure or temperature. The two components work together to ensure that the desired output is achieved. They can be programmed to deliver precise amounts of fluid or gas at predetermined times, allowing for greater control and accuracy. Pic Valves are an essential component of the modern industrial automation system, and are often used to improve safety and efficiency in production processes.
