A PTFE-lined check valve is a passive flow control device designed to prevent backflow in corrosive chemical processing systems. Constructed with a metal body internally coated with polytetrafluoroethylene, it combines structural strength with exceptional chemical inertness, adhering to industry standards for sealing integrity and low friction.
Ensure installation aligns with specified pressure-temperature ratings to avoid liner deformation. Regularly inspect seals for wear or cracking due to thermal cycling. Replace components immediately if leakage occurs or after prolonged exposure to aggressive solvents exceeding design limits.
