A fluid pressure reduction device is provided. The fluid pressure reduction device includes a body and a diffuser. The body defines an inlet, an outlet, and a fluid passageway extending between the inlet and the outlet. The body is made of a first material having a first hardness. A seating area is defined within the body. The diffuser is removably coupled to the seating area and disposed within the fluid passageway of the body. The diffuser defines at least one flowpath for reducing a pressure of a fluid flowing through the fluid passageway. The diffuser includes a second material having a second hardness greater than the first hardness of the first material.

Erosion-resistant fluid pressure reduction device

A fluid control valve trim and seat with a valve plug of a radius of about 0.03 inch, when used in conjunction with a valve seat angle of about 75&#xb0;, results in minimal unbalance area. The valve trim is provided with pairs of anti-cavitation notches. The notches are arranged such that notches of each given pair are angled with respect to one another, and may be further arranged such that adjacent pairs of notches are off-set relative to one another, so as to increase the time fluid spends in the plenum, resulting in proper staging and controlled pressure drop as fluid passes through the valve.
