SPRINGS TO the rescue

When Neles-Jamesbury experienced problems with conventional locking washers used with a gland nut beneath a valve actuation lever, it turned to George Emmott (Pawsons) for the solution. Conventional locking washers situated above and below the handle could not accept the reverse movement of the handle, causing both lever and nut to loosen with consequent gland leakage.

In addition there was a requirement that the operating mechanism for the washer should be visible and the method of operation clearly recognisable. The resultant self-locking washer is made from spring temper stainless steel, and features spring-loaded angled flanges which will flatten to enable tightening by allowing the nut to be turned in one direction only. The flanges then spring back into position, stopping any movement in the opposite direction
