Description

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.
