Production:The multi-stage pressure-reducing valve is suitable for occasions
where the pressure difference is large, which is easy to produce,
flashing, and cavitation. According to the requirements of the
working conditions, multiple different porous cage sleeves are
designed to form a multi-stage pressure-reducing valve.
The standard configuration is an unbalanced single-seat valve core.
The valve core and seat are hardened, which effectively prolongs
the service life of the internal parts. For large-caliber
multi-stage pressure reducing valves, a unique balanced single-seat
valve core structure can be selected.
