Home >> Application >> Chemical Industry
The chemical industry involves a wide range of corrosive, toxic, flammable and chemically aggressive media. Valves play a critical role in process isolation, flow control and system safety.
Corrosive & Aggressive Media
Acids, alkalis, solvents and other aggressive chemicals can cause corrosion, erosion and degradation of valve components.
Material Compatibility
Different chemical media require carefully selected body, trim and sealing materials to ensure compatibility and long-term reliability.
Leakage & Safety Risks
Reliable shut-off and sealing performance are essential when handling toxic, hazardous or volatile chemicals.
Variable Operating Conditions
Chemical processes may involve changes in pressure and temperature, requiring valves to maintain stable performance under varying conditions.
Material selection depends on the chemical composition, concentration, temperature, pressure and operating conditions of the process medium.
