Ductile Iron Flanged Valve Filter Basket Strainer

In large scale industrial piping, protecting expensive downstream equipment from solid contaminants is a critical operational priority. The Veyron Valve Basket Strainer is engineered to provide a high capacity filtration barrier for horizontal pipelines. Unlike standard Y type strainers, the basket configuration offers a significantly larger internal surface area. This increased volume allows the system to trap a higher quantity of debris before requiring a cleaning cycle, which directly minimizes maintenance downtime and prevents pressure drops that could lead to pump cavitation. By utilizing a top entry design, this strainer ensures that the filter element is easily accessible, making it the preferred choice for municipal water lines, cooling towers, and industrial process networks.

Ductile Iron Flanged Valve Filter Basket Strainer

Construction and Material Integrity

The main housing is cast from high grade Ductile Iron GGG40, also known as EN-GJS-400-15. This material is selected for its superior tensile strength and impact resistance compared to standard grey iron. Each unit is coated with a thick layer of Fusion Bonded Epoxy to a minimum of 250 microns. This non-toxic coating provides a dielectric barrier against corrosion and ensures the strainer is suitable for both potable water and raw water applications.

Filtration Dynamics and Maintenance

The heart of the unit is a heavy duty Stainless Steel SS304 basket. The basket is designed with a high open area ratio relative to the pipe diameter, which ensures that the fluid moves through the screen with minimal resistance.

Pressure Management: As seen on the body casting, the unit is rated for PN16 pressure environments. To facilitate safe maintenance, a manual vent ball valve is installed on the top of the cover. This allows technicians to bleed off internal pressure before opening the bolted bonnet.
Debris Removal: A drain port is located at the base of the chamber to allow for the removal of fine sediment and sludge without a full teardown. The top entry design means the basket can be lifted straight out of the body, cleaned, and replaced in minutes.
