Flanged Pilot-Assisted Pressure Sustaining Valve – Z-Tide Industrial BFS Series
The Z-Tide Industrial BFS Series is a premium flanged pilot-assisted pressure sustaining valve designed to automatically maintain a minimum upstream pressure in high-flow water and compatible fluid systems. Featuring an externally piloted control system with a heavy-duty epoxy-coated ductile iron body, the BFS Series continuously monitors inlet pressure and automatically regulates the main valve to maintain a pre-set back pressure regardless of downstream demand. Available from DN50 to DN200 with PN16 flanges and optional ANSI 150 lb or JIS10K drilling, these valves are ideally suited to water distribution, pumping stations, process systems and municipal infrastructure where upstream pressure protection is essential.
Manufactured using a heavy-duty epoxy-coated ductile iron body with bronze piston and precision-machined bronze and stainless steel internal components, the Z-Tide Industrial BFS Series has been engineered for reliable long-term operation in demanding industrial environments. Its pilot-assisted pressure sustaining controller continuously monitors upstream pressure and automatically adjusts the main valve to maintain the selected minimum back pressure, protecting upstream equipment and maintaining stable system operation regardless of downstream demand. The patented cylindrical piston design provides exceptionally high flow capacity while the externally mounted stainless steel pressure gauge allows simple commissioning, adjustment and routine monitoring. The removable pilot controller further simplifies maintenance by allowing servicing without removing the main valve body from the pipeline.
