Another significant aspect of pneumatic control valves is their reliability and durability. Unlike hydraulic systems, which can suffer from leaks and require extensive maintenance, pneumatic systems are often easier to maintain and less prone to failure. The materials used in the construction of these valves are designed to withstand the rigors of industrial environments, ensuring a long service life with minimal downtime. Additionally, pneumatic systems operate at lower pressure levels than hydraulic ones, making them safer in many applications.
