It is available in a range of sizes with flow rates varying from 1 – 20 L/s* making it suitable for various specifications. The Hydro-Valve Slider has the added benefit of an innovative and unique sliding vortex chamber feature for ease of inspection and maintenance.

Used as part of a Stormwater management system it controls the flow from Stormwater attenuation tanks preventing downstream flooding during periods of heavy rainfall.
The JFC Hydro-Valve Sliders is manufactured to customer specifications and custom designed to achieve a specified design flow rate at a given head height. It fits into one of the following manhole types depending on the specification:

Manufactured to ISO 9001:2008 quality assurance systems
The Hydro-Valve Slider controls Stormwater flow by hydraulic effect. At low flow rates water enters through the inlet and passes through the vortex chamber to the outlet without restriction. As the flow rate increases water enters through the inlet with sufficient energy to create a vortex in the chamber which results in a considerable pressure drop between the inlet and outlet which restricts the flow to the allowable discharge. It therefore operates automatically with no moving parts and no external power source.
