A: Valve trains (or fuel trains or gas trains) control the flow of gasses for industrial equipment, such as furnaces, ovens, dryers and boilers, making them a crucial component in assuring operational safety and energy efficiency. A poorly designed or inadequately maintained system can lead to explosions, fires, asphyxia and burns. For that reason, Rockford Systems’ valve trains feature industrial-grade construction and are universally wired to accept most North American control systems. Optional features allow for common adaptations such as safety valve proving, climates down to -20°F, 230V controls, lockable valves, and pilot-line assemblies. The designs feature industry-leading components and are engineered to meet or exceed NFPA, NEMA, CSA, UL, FM and other globally-recognized safety standards.
