Product Description
The BT-03 / BG-03 series is a pilot-operated relief valve for main-system pressure protection — the valve that stands between your power unit and a burst hose. The pilot stage controls a large main poppet, so the pressure-versus-flow curve stays flat: the setting holds from idle flow to full flow with minimal pressure override, and the valve reseats tightly near the set point. Two mounting styles cover every installation: BT-03 with pipe-thread ports for line mounting, and BG-03 on the standard ISO 6264 subplate for manifold systems. The S-BT/S-BG variants add a solenoid vent that dumps the pilot stage on command — the standard way to unload a pump at idle or switch between two pressure levels in accumulator and two-pressure circuits. Interchanging with the Yuken BT/BG-03 series, the valve is individually pressure-tested on a calibrated bench before packing with anti-rust treatment. Typical duties span presses, injection molding machines, steel plant auxiliaries and marine deck machinery — send your flow and pressure setting for a quotation within 24 hours.
