High temperature services
Metal seated knife gate valve applications such as thermal or high cycling, or vibration situations can cause the packing gland bolts to loosen. In these situations, live loaded packing can be provided. Extended packing gland bolts or studs are used in conjunction with stacked Belleville washers. When tightened, the washer stacks impart a force into the gland, maintaining compression on the packing. Live loaded packing requirements vary by manufacturer; therefore the valve may be required for completion.
