Trenchless Technology: valve release via 5m spindle extension

IMGP0594
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.
