AbstractOperating conditions of shutoff valves are studied. The main shortcomings of surfacing methods by manual and automatic arc welding at production of fittings saddles are listed. The way of production of locking knot saddle of the high pressure valve by method of dynamic hot pressing of previously baked preparation of the necessary structure in the “in-sity” case is offered.
