T-T Flow are professionals in the design, manufacture, and distribution of engineered valves and associated ancillary equipment to the water, process and allied industries.
Our flexible approach allows the supply of just a single valve, a combination of stock products or the ability to work with our clients to provide a complete engineered valve package, along with ancillary equipment. Meeting your specifications, combining our products and services with that of other T-T divisions, we are able to offer cost-effective, customised, single-sourced packages.
Designed in the UK, our in-house team of experienced engineers, utilise the latest design software, continually re-evaluating products and materials to ensure that relevant international and regional standards, and market requirements are met.
T-T Flow heavily invest in research and development.The highest production standards are achieved through considerable resource investment in the latest equipment and techniques, including finite element analysis and rapid prototyping. In-house test facilities allow for full product testing including pressure (both seat and shell), mechanical, electrical and endurance.
What have we supplied?
DN250 PN16 Actuated Plug Valve for flow control
When it comes to flow control T-T Flow have the answer. When asked to supply a valve to modulate a wastewater pipeline we provided the perfect solution. The Towcester STW within the Anglian Water region was undergoing an upgrade due to increased demand.
An eccentric plug valve with close-coupled modulating electric actuator that would effortlessly integrate into the clients’ site protocol was supplied.
DN150 PN40 Gate Valves for a high-pressure system
The construction of the US$18M Loch Eilde Mor hydro-electric scheme in Scotland required some custom high-pressure isolation valves.
T-T Flow designed and manufactured three BS5163 DN150 metal seat gate valves with a pressure rating to 40 Bar, which also had an ISO5210 interface for actuation. Given the application and to avoid contamination only WRAS compliant materials were used.
2” Duplex stainless steel air valves for a corrosive environment
T-T Flow supplied specialist air valves to the US$25M Falklands Mare Harbour improvement scheme. Due to the arduous salt-laden environment, careful product selection was vital.
We were tasked to provide three function air valves with an integral anti-surge mechanism to minimise the potentially damaging effects of water hammer. The valves were constructed in Duplex stainless steel for increased corrosion resistance, and used WRAS approved materials.
High Performance Knife Gate Valves for Anaerobic Digestion
T-T Support UK municipality, Severn Trent Water, with US$27M food waste to green energy plant. The site processes 50,000 tonnes of food waste a year to produce renewable gas that is pumped into the distribution network. The company serves around eight million customers across the Midlands and mid-Wales.
T-T were invited at an early stage to support project design engineers in product selection to optimise the system. Consequentially 87 stainless steel (grade 316L/1.4404) lugged knife gate valves were supplied ranging in size from DN150 to DN300; many having pneumatic cylinders with solenoid valve, inductive limit switches, and junction box.
