Description

Flanged Ductile Iron Normally Open Solenoid Control Valve – Z-Tide Industrial NOBFE-D Series

The Z-Tide Industrial NOBFE-D Series is a premium flanged 2/2 way normally open ductile iron solenoid control valve designed for reliable control of water and compatible non-corrosive fluids in large bore pipelines. Featuring an externally piloted pressure-assisted piston design with patented anti-water hammer technology, the valve remains open during normal operation and closes when energised, making it ideal for fail-safe applications. Available from DN50 to DN1000 with PN16 flanges and optional ANSI 150 lb or JIS10K drilling, the NOBFE-D Series delivers exceptionally high flow rates while providing reliable operation in water treatment, pumping stations and industrial process systems.

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 NOBFE-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 operation. The removable external pilot assembly allows maintenance without removing the main valve body from the pipeline, reducing downtime and simplifying servicing. Designed for fail-safe applications, the normally open configuration ensures uninterrupted flow during normal operation while providing dependable shut-off when electrically energised.

Ordering information
