When should the regular bolts of a break-type shut-off valve be removed?
Thread Content
Enterprise filling stations are generally equipped with breakaway valves. Breakaway valves of this type come in two designs: those with full-through holes and those with semi-through holes. The semi-through-hole design uses breakaway bolts, while the full-through-hole design uses regular bolts. Some companies fail to remove the regular bolts of the break-type shut-off valves; are these regular bolts intended for securing the valve during transportation, and should they be removed after installation?
Yes, the regular bolts in the break-type shut-off valve are used for shipping from the factory or for installation and fixation. Such ordinary bolts are generally used to maintain the stability of the equipment during transportation and installation; they should be removed before the equipment is put into formal use, otherwise it will prevent the valve from functioning properly as intended for safety shutdown. Therefore, once installation at the site is complete and it is confirmed that the valves are securely installed, these ordinary bolts should be removed promptly, leaving only the breakaway bolts that meet the design requirements, to ensure that the pull-out valve can function properly. .
