Relisafe- PR Sample Pressure Reducing Valve

Forbes Marshall's SPRV is a rod-In-tube type pressure reducing device. It serves a combined function of pressure reduction and flow modulation. As the high pressure sample is forced to pass
through the narrow annular region between the rod and tube, the frictional resistance causes the pressure to drop while at same time modulating the flow.
