• Water management

    By water management, we mean the prevention of flooding, the provision of sufficient ground and surface water and guaranteeing the quality of the water. Under ever-changing conditions, water management faces challenges such as: storm water, level rises, standing water or contaminated water. Water is crucial for the well-being of our society and we like to think about sustainable solutions to increase the manageability, safety, quality and sustainability of our water.

Standing water

What is standing water and why is it dangerous? Standing water is water that has stood still for more than four hours. Standing water can occur within a pipe network, within the infrastructure of surface water, reservoirs, storage tanks and pipes of residential buildings. It is often caused by waiting times due to installation or maintenance, blockages, flooding or irregular water use. Standing water is dangerous, because it provides the ideal living conditions for water bacteria and germs. These can pose a health risk to the person exposed to them. In some circumstances, it is also possible for contaminated water to flow back into clean pipework, resulting in a loss of quality in a production process.

Standing water can be partially avoided within a pipe system by means of regular flow. Reliable equipment and manageability are of added value to limit the risks. Due to causes such as: blockages, flooding or long-term maintenance, the risk of standing water can never be completely excluded. This makes it important to protect clean pipework against backflow of potentially contaminated water.

Prevent backflow

The rubber duckbill check valve is the ideal solution to prevent backflow. Check valves are available in almost every industrial application as check or one-way valves. Check valves perform a vital function to prevent backflow and ensure efficient operations. The rubber check valve creates a physical barrier between potentially contaminated fluids and clean pipework. With a single inlet and outlet, the check valves are operated by a differential pressure. Above a certain upstream pressure, the valve will open automatically without the need for any other intervention. With partial or complete underflow on the outlet side, the valve closes due to the pressure on the membrane. This completely eliminates the risk of backflow. View the product page.

Prevent water hammer

What is water hammer? Water hammer is a phenomenon that can occur when starting or interrupting a flow in a closed pipe. The energy of the flow is expressed in a pressure wave through the pipe. When the flow is abruptly interrupted or started, sudden pressure differences occur. These pressure differences can result in vibration, equipment failure, wear, noise pollution and ruptured pipes. In the worst case, water hammer leads to unexpected shutdown of processes or very dangerous situations.

Compared to metallic fittings, rubber fittings can cope much better with the shocks and vibrations that occur in pipes. Convenient use can be made of rubber valves or rubber expansion joints to achieve metal-to-rubber collisions, rather than metal-to-metal collisions. Resulting in an extended service life of the piping and a reduced chance of unexpected failure.

The most ideal solution to eliminate water hammer are the rubber duckbill check valves. Non-return valves are used to prevent backflow and thus also make it possible to control pressure differences. In addition to resisting water hammer and vibration, they operate completely passively due to a pressure difference. The rubber material is specified according to the process pressures and opens automatically by a certain positive pressure. Back pressures result in a closed position, which excludes backflow. They are therefore often used in series or behind pumps to absorb water hammer and protect crucial equipment. View the product page.
