This type of Stainless Steel 3 piece BSP / NPT threaded check valve is designed as an in line spring check valve. Suitable for a wide range of media including steam, water, oil and many others. This stainless threaded check valve can be installed in any orientation as it has a spring backing.

The check valve of stainless steel is 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 check valve has a metal to metal seat so a bubble tight seal will not be formed at lower pressures.

The compact 3-piece stainless check valve body design allows a flow exceeding the pipe area to minimize flow losses and maximize efficiency. In addition, it is a cost-effective alternative to traditional 3-piece ball valves. The unique spring loaded, stainless steel disc and guiding system insures quick closing of the valve, which minimizes water hammer.

The stainless check valve is an alternative  of the 3 piece ball valve and is designed for simple installation and will operate well in any position. The Valve is available with NPT or BSP threaded connections as well as with socket end or butt welding ends connections.

FAQ

What materials are used in the construction of the check valve?
The check valve is constructed from high-quality stainless steel, ensuring durability and resistance to corrosion.
Can the check valve be installed in any orientation?
Yes, the stainless threaded check valve can be installed in any orientation due to its spring backing.
How is maintenance performed on the check valve?
Maintenance can be performed by undoing the tie rods, allowing for removal without unscrewing the threads.
EXPERT ADVICE: Ensure that the check valve is installed correctly to avoid leaks, especially since it has a metal to metal seat which may not provide a bubble-tight seal at lower pressures.
