ABSTRACT:
A pressure compensating, two-stage bypass metering valve assembly including a valve body having side inlet and outlet ports and a bottom bypass port, and a hollow plug rotatable in the body and having inlet and outlet metering orifices and an end opening aligning with the bypass port. A pressure responsive variable orifice bypass valve unit is mounted adjacent the bypass port and cooperates with the metering orifices to prevent any significant increase in fluid flow from the valve outlet even though fluid inlet pressure may fluctuate widely.
