FCT Valve’s diaphragm control valves are designed to regulate flow in high-purity, corrosive, or abrasive process environments. These valves feature a flexible diaphragm that isolates the working fluid from the mechanical actuator and internals, providing leak-free, contamination-resistant control suitable for clean or chemically aggressive systems.
