Tideflex

Backflow Control That Doesn’t Back Down

Tideflex check valves transformed backflow prevention with their all-elastomer design, eliminating the mechanical failures common in traditional flap gate valves. Their duckbill-style valves are known for sealing around trapped debris and performing in harsh, debris-laden, or corrosive environments.

Maintenance-free check valves built for backflow prevention and mixing applications.

Tideflex valves operate using only system pressure, with no external power or actuation required. Their curved bill and flexible elastomer construction enable reliable sealing, even with suspended solids or variable flow. Trusted for their longevity and passive operation, Tideflex systems are widely used in water treatment, stormwater, and industrial effluent control.

Did You Know?

  • Tideflex’s curved bill was inspired by the motion of a fish mouth.
  • Tideflex check valves require no maintenance and have zero moving parts.
  • Hundreds of thousands of Tideflex valves are installed around the world.

Check Valves

Tideflex Duckbill Check Valves deliver low head loss and reliable sealing, even at minimal flow rates. The patented Curved Bill design improves closure while the elastomer-reinforced body resists corrosion, rust, and UV exposure. With no moving parts, these valves operate maintenance-free over along, cost-effective service life.

Mixing Systems

The Tideflex Mixing System (TMS) utilizes variable orifice check valves to generate high-velocity jets, enhancing water quality by eliminating stagnation, short-circuiting, and dead zones. Requiring no maintenance or external energy, the TMS has been extensively validated in field tests and modelling studies.

Aeration Systems

Tideflex Aeration Systems combine mixing, backflow prevention, and oxygen transfer in a compact design. They isolate wastewater from the air manifold, preventing clogging and allowing intermittent blower use. This reduces operational costs while improving treatment performance in both municipal and industrial applications.

Effluent Diffuser Systems

Tideflex Diffuser Systems feature all-rubber, corrosion-resistant construction that prevents marine intrusion and fouling in outfall pipelines. Their unique valve design increases discharge velocity for improved mixing, while the self-actuating elastomer elements ensure maintenance-free operation in harsh marine and inland environments.
