Abstract: A flow control valve includes a valve body with inlet and outlet ports, and an intermediate chamber therebetween. The valve further includes a static flow rate regulator for the fluid, accessible from outside the valve body and adapted to vary the cross-section of a passage orifice between the inlet and the outlet of the valve.
