Installation Location:
●Installed in transmission/distribution pipelines or bypass lines.
Main Applications (by Control Function):
●Pressure sustaining / pressure relief control: Stabilizes upstream (inlet) pressure.
●Pressure reducing control: Stabilizes downstream (outlet) pressure.
●Flow control: Maintains a constant flow rate.
●Combined pressure sustaining & pressure reducing control: Simultaneously controls both inlet
and outlet pressures.
Product Features:
●Axial-flow passage design ensures stable and precise flow control.
●Multi-orifice structure forms high-velocity water jets that dissipate energy through
mutual impingement.
●Movable sleeve controls the number of effective orifices to meet various operating requirements.
●Energy dissipation is completed entirely within the orifice tube, reducing vibration and noise.
●Prevents erosion of the valve body’s inner surface, extending service life.
Operating Principle:
●As the fluid passes through the multi-orifice sleeve, it is guided to form high-velocity jets that
collide internally to dissipate kinetic energy.
●The movable outer sleeve adjusts the number of open orifices as required, enabling precise
flow control and enhanced durability.
Design Characteristics:
●Customized helical orifice arrangement:
▶Orifice diameter and quantity can be optimized based on hydraulic analysis. All orifices are arranged
in a helical pattern to ensure continuous and stable control.
●Advanced conical orifice design:
▶Conical orifices allow smooth acceleration of flow into jets entering the orifice tube, providing
precise flow control and effective energy dissipation through jet impingement.
