71000, one-saddle angular valve

The valve of a series 71000 is developed for critical parameters of operation at high temperatures, pressure, on the coked and sticking working environments. The flowing part is executed by the most streamline and has no stagnant zones that minimizes an erosion and a possibility of formation of a deposit. The opening for supply of flushing liquid is provided in a mouth of the case that is necessary during the work on the polluted environments or in oil processing for prevention of coking up.
