Description

Flanged 304 Stainless Steel Normally Open Solenoid Control Valve – Z-Tide Industrial NOBFE-S Series

The Z-Tide Industrial NOBFE-S 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 from 304 stainless steel throughout the main valve body and internal components, the NOBFE-S Series provides excellent corrosion resistance together with exceptionally high flow rates for industrial process systems, water treatment, cooling circuits and steam services.

Manufacturing quality

Manufactured using a heavy-duty 304 stainless steel body with stainless steel piston, seat and internal components, the Z-Tide Industrial NOBFE-S 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. The normally open configuration ensures continuous flow under normal operating conditions while providing reliable shut-off when electrically energised.
