Check valves are used for flow switching, diverting and converging in pipelines, mainly classified as **T-type** and **L-type**.- T-type: for flow diversion, convergence and direction switching.- L-type: for switching between perpendicular flow channels.For special production needs, reengineering is often applied by combining features of both types.- **ANSI check valves**: all-metal disc or rubber-lined disc.- **Carbon steel check valves**: integrated functions of lift check valve and globe valve, for boiler feedwater and steam service.- **High-temperature check valves**: automatic valves preventing backflow, pump reversal and medium leakage.In special cases, users need an L-type valve to switch flow **and** shut off three lines at once.To avoid extra globe valves and complex systems, we redesigned the L-type check valve with **3 or 4 seats** and a large ball, enabling both flow switching and triple sealing.Reengineered check valves better meet special industrial requirements.Tianjin Kaivis Valve Manufacturing Co., Ltd.
