Abstract
A toggle gate valve having a double block and bleed retractable sealing configuration which utilizes accurately positioned steel inserts as trim assembly guide plates to permit a significant reduction in valve body machining. The valve body as well as removable upper and lower bonnets form a pressure boundary that houses a toggle link actuated seal plate to close the valve and a through-conduit that is coaxially aligned with the input and output ports when the valve is opened. A novel stem configuration and removable through-conduit permit field servicing of the trim assembly (plug and seal plate) by means of access through the lower bonnet/body interface.
