Flanged Ductile Iron Solenoid Valve – Z-Tide Industrial BFE-D Series
The Z-Tide Industrial BFE-D Series is a heavy-duty flanged 2/2 way normally closed solenoid valve designed for high-flow control of water and compatible non-corrosive fluids in large bore pipelines.
Featuring a pressure-assisted externally piloted piston design with patented anti-water hammer technology, the BFE-D provides exceptionally high flow capacity with controlled 3–5 second opening and closing to help reduce hydraulic shock and pressure surges.
Manufactured from epoxy-coated ductile iron with bronze piston and seating components, the BFE-D is available from DN50 to DN1000 with PN16 flanges as standard. Optional ANSI 150 lb, JIS10K and alternative flange standards are also available.
Ideal for water treatment, pumping stations, industrial process water, cooling systems, irrigation, reservoir control and municipal water infrastructure.

Manufacturing quality
Manufactured using a heavy-duty epoxy-coated ductile iron body with bronze piston, bronze seating components and stainless steel internal parts, the Z-Tide Industrial BFE-D Series has been engineered for reliable long-term operation in demanding industrial environments. Its patented cylindrical piston design and externally piloted control system provide exceptionally high flow capacity while significantly reducing water hammer during valve operation. The removable external pilot assembly simplifies maintenance without disturbing the main valve body, making the BFE-D Series an excellent solution for large pipeline installations where reliability, ease of servicing and long service life are essential.
