The hydraulic value mod ING-EL is an automatic shut-off valve that allows to open and close the line, ensuring excellent reliability and versatility. The entire line of models has the option of having a manual flow controller or not

The TIC12 controller represent the new generation of well-known TIC backflush controller produced by Tecnidro since 2005.

Saving water resources is nowa priority objective in the management of distribution networks, but remains difficult to achieve without the support of specific and reliable automation technologies. With over 30 years of experience in the production of hydraulic equipment, TECNIDRO introduces to the market an innovative solution proposing HYDRONET system, based on the latest LPWAN radio transmission technologies. HYDRONET has been specifically designed for public water management networks on geographical areas as well as for plants with a more limited extension belonging to farm and private companies.

Saving and optimising water resources is now a priority objective in the management of the irrigation process, and the new TECNIDRO control unit represents an evolution compared to traditional control units thanks to its simple management via APP on a smartphone or tablet, its simple installation on the TECNIDRO valve line and the possibility of operating not only on the basis of delivery time but also according to water volumes.

The valve reduces high upstream pressure to a pre-set lower and constant downstream pressure level, regardless of fluctuating flow or varying upstream pressure. A hydraulic regulating pilot drives the valve. The pilot is able to detect upstream pressure values and regulates closing steps of the valve until the pre-set pressure value is restored.

The valve opens fully or shuts off in response to electric signals. The valve is controlled by a solenoid that allows control liquid to flow in the upper chamber in order to close the main valve or, alternatively, drains upper chamber in order to open the main valve.

This valve protects pumps and pipes from pump startup and shutoff pressure surges due to power failure. Pump off means valve normally closed. If pump starting cause pressure surge, the pilot smoothly opens the valve to limit pressure rising. Quick relief valve opens due to both pressure rises and falls, fully reducing any pressure fluctuation.

The valve maintains downstream pressure over a pre-set minimum value, regardless of fluctuating flow or varying upstream pressure. Otherwise the valve may open gradually to allow surplus water flow outside the system in order to maintain system pressure to a maximum pre-set value. A hydraulic regulating pilot drives the valve. The pilot is able to detect upstream pressure values and regulates closing steps of the valve until the pre-set pressure value is restored.

The valve closes totally the pipe line when back flow occurs. The valve is complete with an hydraulic control circuit able to regulate operation’s speed during closing, preventing surge.

This valve controls water level in high level reservoirs to avoid overflow, without any external control system like float control etc. The valve remains completely open until the closing input is transmitted by the 3-ways piezometric altitude pilot.
