Tideflex valves - no problem solving difficult scenarios

Tideflex valves - no problem solving difficult scenarios

Square openings, existing fixings, angled walls, difficult access? Tideflex can engineer solutions for problematic retrofit and flap valve replacements every time.

MeasurIT have been providing solutions to drainage outfall valve problems for almost 20 years. It doesn't matter if you need to retrofit a valve to a square opening, align it with existing fixings or drilled holes, or fix it to an angled wall - we have come across almost every scenario conceivable, and engineered a solution that works.

Tideflex check valves have been in production since the 1980s and are being continually improved as technology evolves. Tideflex Technologies engineers are available to advise on solutions to non-standard applications and provide design drawings for valve installations.

Our rubber duckbill valves come in flanged and non-flanged versions and can be clamped or drilled onto pipes depending on the scenario. A thimble plate (straight or angled) is used to attach the valves to headwalls - even square cuffs are possible.

Here are a few typical scenarios where we have been called upon to provide a workable solution....

Angled Headwall on a Harbour Beach

This square culvert outfall in Dun Loaghaire Coal Harbour was subject to constant build-up of silt and stones. The existing headwall is angled and the Tideflex check valve is bolted on with an angled thimble plate - a fairly common scenario for us.

Flap Valve Replacement on a Beach

This is a problematic outfall in Waterford county where the existing flap valve solution is unable to cope with the constant shifting of beach sand - sometimes being completely covered as the sea washes sand up on to the beach, or wedged open with sand.

We are in the process of manufacturing a solution taking into account the existing square opening with round overflow in the headwall. Obviously the sand situation will not be a problem for the Tideflex duckbill valve, which is proven over many years to be self-clearing of sand in similar situations.

Tideflex Valves Array on CSO Outfall

Certain situations require the use of multiple Tideflex valves combined in an array. This is an example of a valve array on the outfall of a combined sewer overflow. The Tideflex valves are secured to a plate that is then fastened to the headwall.
