Description Size 40 … 300 Component series 1X Maximum operating pressure 16 bar Maximum flow 50000 l/min Features For flange connection Flange connection according to DIN EN 1092-2 type 21 4 cracking pressures Product description Valves type L-S are check valves for pipeline installation. They are particularly suited for high flows. The valves basically consist of pipeline installation housing (1), main spool (2), spring (3) and cover (4). In direction P → T the main spool (2) can be opened by the flow against the spring force. In direction T → P, however, the line is locked leakage-free by the main spool (2). Notice: Observe flow direction and flow direction indicator.
