PVDF Sediment Strainer
A PVDF Sediment Strainer is a device made from Polyvinylidene Fluoride (PVDF) designed to filter out solid particles, debris, and sediment from liquid flow in piping systems, protecting downstream equipment like pumps, valves, and meters. These are meant to capture any solid contaminants that may sometimes be in the line. Solenoid valves and other devices with small holes, such as pumps or control valves, are protected by a PVDF Sediment Strainer. The filter screen is easily replaceable and available in a variety of mesh sizes.
The pump and meter are protected by a PVDF sediment strainer, which removes suspended particles and contaminants. The position of the screen can be easily determined due to its transparent thermoplastic structure. The optional in line cleaning valve flushes collected particles from the strainer port. It is easy to install or repair without enlarging the pipeline. A great filtering capacity and minimum pressure drop are two of its key features. As a result of the transparent PVDF sediment strainer, the condition of the filter screen can be easily assessed.
