Description
This vertical Lift Check Valve (Class – 1) from Leader covers 15 mm to 100 mm. Fitted to prevent flow reversing when a pump stops or a line depressurises. Orientation matters: a swing pattern needs the correct attitude to seat properly, so confirm the intended mounting before ordering. The LTB-2 gunmetal body to IS 318 resists dezincification, which is why gunmetal remains the default for potable water rather than a cheaper brass. Parallel BSP threads — the usual small-bore connection, and quick to replace in service. Size-by-size catalogue numbers and pricing appear in the table above.
