Invicta Valves Limited Site Solutions, has successfully completed a Rapid Gravity Filter (RGF) valve replacement scheme at a large Water Treatment Works for clients, Affinity Water. The scheme was competitively bid and had an approximate value of £230k.
Work on the scheme began in August 2016 and was completed in October 2016. The Invicta Site Solutions Team carried out the works utilising the extensive product range of the world leading valve manufacturer and parent Company, AVK Group.
The scheme specification involved replace, supply and fit all valves, penstocks and actuators on 8 RGF’s which in total included:
32 No. Butterfly Valves (4 per filter)
8 No. actuated Penstocks
8 No. manual Gate Valves
Invicta Site Solutions National Sales Manager, Alex Philo explained the team’s approach, “This was a challenging scheme and we were able to draw on our extensive expertise and skill sets as well as utilise the product and resource capability that being a member of the AVK Group brings. All products, M&E, steelwork, and supplementary services were provided ‘in-house” – This is what I believe makes the Site Solutions offering unique, we can supply a full turnkey solution, from supply, design, fitting, and maintenance. We also offer a refurbishment offering within our workshops.”
The project also involved work on the valve’s actuators which were situated below floor level, in chambers, making access difficult and cumbersome. Previous commissioning and maintenance works had to be conducted under Confined Space processes and conditions – not at all ideal.
After comprehensive consultation with Affinity Water, the solution identified and recommended by the Invicta Design Team, was to bring the actuators above floor level, making the works easier and safer to access and perform.
Invicta installed open mesh floors above all of the valve chambers and repositioned the actuators at waist height through the mesh floors, using extension spindles.
“This solution will benefit Affinity Water for many years to come, not only will works be easier in the future because we have negated the need for Confined Space working, but also all of the products supplied by the AVK Group are maintenance free – we believe this is a robust and resilient solution.” Alex continued.
The scheme also required refurbishment work including the replacement of existing pipework, flow metres, penstocks, actuators, gearboxes, extension spindles and pedestals as well as all associated electrical works.
Stuart Smith, Affinity Water Production Engineer and Project Manager for the scheme, said, “There has been a positive and collaborative approach between us and the Invicta Site Solutions teams on the scheme. The combination of innovative thinking and a resilient solution meant that we could move forward confidently.”
