RTV Forged Swing Check Valves, also known as one-way valve, non-return valve and so on, is an automatic valve opening and closing itself by the force of flowing medium. And Forged check valve is mainly used for preventing the backflow of medium, the reversal of pump & its motor and the discharging of container. By different structure, it could be divided into forged swing type check valve & forged lift type check valve; If by different connection, it could be flanged forged check valve, socket welded forged check valve and etc.
