A range of both HDPE and stainless steel flow controls, regulators and orifice plates for different applications in stormwater are available. Each unit is individually designed and built to order.
The Hydrovalve HDPE vortex flow controls are designed for discharge rates between 1-200 L/sec depending upon specification. Mountings are available to fit Oaklands HDPE tanks or concrete chambers up to 1800mm diameter or rectangular manholes.
The stainless steel vortex flow controls are usually manufactured using corrosion resistant Grade 304 stainless steel and designed and built to meet specific site requirements.
All vortex flow controls are fitted with a manual draindown/bypass device in the unlikely event of a blockage.
