316 Stainless Steel 2 piece BSP threaded in line lift check valve. Suitable for a wide range of media including steam, water and oil. Please bear in mind that this is a metal to metal seat so a bubble tight seal will not be formed at lower pressures. Can be installed in any orientation as it has a spring backing. Great for a simple backflow/backpressure preventer where stainless steel is required.
