This appraisal is for a range of valve spindle extensions in lengths of 150, 225 and 300mm, suitable for operation on gate valves up to and including DN 300. This Issue 2 is a replacement for the previous version of the appraisal which had reached its 5-year expiry date.
The black coloured valve spindle extensions are injection moulded from a high strength composite material, which provides for a single piece homogenous product.
Each spindle extension is fitted with a M12 Grade 316 stainless steel bolt to allow retention on to the spindle cap.
The extension spindles are lightweight and inherently corrosion resistant with a high level of dimensional accuracy.
