ABSTRACT:
The invention provides an erosion resistant pressure reduction valve or choke comprising a valve housing (1,22) defining a valve chamber (2) connected with an inlet (3) and outlet (4), a stationary first valve body (6,17) arranged in the chamber, and a second valve body (7,18). The second valve body is arranged so as to be turnable or displaceable relative to the first valve body by means of a spindle or the like (14,23). The first and second valve bodies are each provided with corresponding flow-through apertures (19,28). Flow through the valve is regulated by turning or displacing the turnable/displaceable second valve body relative to the first. The apertures in the valve bodies (6,7,17,18) are provided with casings (15,20) made in one piece of polycrystalline diamond.
