👉 Valve fluid, also known as sealant or lubricant, is a specialized liquid used in hydraulic and pneumatic systems to facilitate smooth operation and longevity of valves. It serves multiple purposes: it reduces friction between moving parts, prevents corrosion and wear by forming a protective barrier, and ensures proper sealing to maintain system integrity. Typically, valve fluid is designed to be compatible with the specific materials used in the valve and its environment, and it often includes additives for enhanced performance. This fluid is crucial for maintaining the efficiency and reliability of hydraulic and pneumatic systems by minimizing leaks and ensuring consistent operation.
