The Problem: a horizontal 600mm gate valve used to throttle pumps at a major treatment facility was seized at the 25% open position. The valve was situated 4m high and operated via a chain and wheel assembly.
The Solution: due to the risk of possible damage to a critical asset, Hydrosave’s valve release technology was selected due to its ability to release valves using minimal torque at levels under the safe design specification for a valve. A scaffold tower was erected around the valve, the chain hub removed and the ‘clever valve release’ system installed.
A waste water treatment works was being commissioned as part of the hand over process after a planned refurbishment project. It became apparent that a ‘Tri-Plug’ valve which was part of the Ferrous dosing system had become seized. Continue reading →
A 9″ washout valve situated on a service reservoir required releasing in order to drain down the tank sufficiently to allow safe access. Although this was a small valve, the challenge was to release through 5 metres of small diameter spindle extensions. This proved not too be a problem for the Hydrosave Clever Valve Release system which transferred 230Nm or torque to take up the backlash on the extensions and focus the vibration toward the open position. As with all valve release projects performed by Hydrosave a torque assessment was completed and the results stored on the web based reporting facility for future reference.
A major UK Water Company insisted on the Hydrosave valve assessment and valve release services to improve their knowledge, reduce their risk and quantify the operability of valves during the contingency planning for a major CAPEX scheme. Continue reading →
