Description

Flanged 316 Stainless Steel Normally Open Solenoid Control Valve – Z-Tide Industrial NOBFE-SS Series

The Z-Tide Industrial NOBFE-SS Series is a premium flanged 2/2 way normally open stainless steel solenoid control valve designed for reliable control of water, steam and compatible process 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. Manufactured with a 316 stainless steel body for maximum corrosion resistance, the NOBFE-SS Series delivers exceptionally high flow rates for demanding industrial process systems, chemical processing, food production, water treatment and hygienic applications.

Manufacturing quality

Manufactured using a heavy-duty 316 stainless steel body with precision-machined stainless steel internal components, the Z-Tide Industrial NOBFE-SS Series has been engineered for demanding industrial environments where corrosion resistance, high flow performance and dependable fail-safe operation are essential. 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 rapid maintenance without removing the main valve body from the pipeline, reducing downtime and simplifying servicing. Designed for fail-safe operation, the normally open configuration ensures continuous process flow under normal conditions while providing reliable shut-off when electrically energised. The optional FKM, EPDM and FFKM sealing materials further extend the valve's suitability across a wide range of industrial and hygienic applications.
