When a critical water treatment works in Wigan required an overhaul, T-T Flow was entrusted to supply two large diameter gate valves to help ensure the continued efficient supply of potable water in the northwest of England.

The Problem

Wigan Wastewater Treatment Works is an important facility operated by United Utilities, who are responsible for the delivery of potable water and the capture and treatment of wastewater throughout the region.

In order to ensure the continued efficient delivery and treatment of water, there was a requirement for two new large diameter gate valves to meet the required specification and facilitate safe, easy and reliable operation.

The Solution

T-T Flow, the specialist valve division of T-T Pumps, was engaged to supply a pair of DN500 MSGV isolating wedge gate valves measuring 500mm in diameter. These are rated to withstand 16 Bar pressure and come with customised operating equipment utilising intelligent actuation. 

As the valves would be installed beneath steel grating, each valve was supplied with an extension spindle bringing the operating element (electric actuator) to an ergonomic position for safe and easy operation.

T-T were selected due to their ability to project manage the whole supply, offering an efficient single point of contact for the client.  T-T Flow holds extensive stocks of Aquaflow metal seated wedge gate valves, which for this size feature superior weld deposit seating faces. Furthermore, T-T’s in-house fully equipped workshops permitted the fabrication of site-specific extension spindles, and the mechanical and electrical functional testing of electric actuators.

In addition to metal seat wedge gate valves for wastewater duties, T-T Flow also stocks a wide range of WRAS approved resilient gate valves, check valves, air valves and pressure reducing valves engineered for potable water solutions.
