The TECFLOW duckbill check valve with carbon steel flange is a durable, maintenance free, non-return device that automatically prevents backflow while reducing pipeline noise and thermal stress. Made from robust elastomeric materials to resist corrosion, it operates between -15°C and 80°C, purely on pressure differentials and is widely used across industries like water supply and chemical engineering in sizes from DN15 to DN2000.
Available in the UK exclusively through Automated Environmental Systems.
Valves are ordered direct from the supplier, please call before placing your order as longer lead times will apply.
Prevents backflow, the non-mechanical operation requires no maintenance or energy costs, very quiet operation without water hammer
