Flanged Pilot-Assisted Pressure Reducing Valve – Z-Tide Industrial BFR Series
The Z-Tide Industrial BFR Series is a heavy-duty flanged pilot-assisted pressure reducing valve designed to automatically reduce and maintain stable downstream pressure in high-flow water and compatible fluid systems.
Featuring an externally piloted pressure-assisted piston design, the BFR continuously monitors downstream pressure and automatically modulates the main valve to maintain the selected outlet pressure despite fluctuations in inlet pressure or downstream flow demand. This helps protect downstream pipework and equipment while providing stable system pressure.
Manufactured from epoxy-coated ductile iron with bronze piston, cylinder and seating components, the BFR combines exceptionally high flow capacity with robust industrial construction. Available from DN50 to DN500 with PN16 flanges as standard, with ANSI 150 lb, JIS10K, JIS20K, PN10, PN20 and alternative flange standards also available.
Ideal for industrial water distribution, cooling water systems, process water, municipal networks, pressure zoning, pump discharge control and other large-bore pressure regulation applications.

Manufacturing quality
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 BFR Series has been engineered for reliable long-term operation in demanding industrial environments. Its pilot-assisted pressure reducing controller continuously monitors downstream pressure and automatically adjusts the main valve to maintain the selected outlet pressure, regardless of variations in inlet pressure or system demand. The patented cylindrical piston design provides exceptionally high flow capacity while the external pressure gauge allows quick visual confirmation of the regulated outlet pressure, simplifying commissioning and routine maintenance.
