316 Stainless Steel 3 piece BSP threaded in line lift check valve. Suitable for a wide range of media including steam, water, oil and many others. Can be installed in any orientation as it has a spring backing. Ideal for use in fixed pipelines as the valve can be removed by undoing the tie rods to allow for maintenance and cleaning without unscrewing the threads. Specifically designed check valve for long life, simple operation and easy maintenance. Please bear in mind that this is a metal to metal seat so a bubble tight seal will not be formed at lower pressures.
