A fluid control valve for an inline fluid control system comprising a housing having a fluid inlet and a fluid outlet, the housing having a rectangular shaped fluid passage for fluid to flow therethrough, the housing having a first cylindrical passage located therein and a second cylindrical passage located therein with the first cylindrical passage and the second cylindrical passage located in coaxial alignment with each other, the first cylindrical passage having a first diameter and second cylindrical passage having a second diameter with the first diameter larger than the second diameter and a stepped plunger slidably located in the first cylindrical passage and the second cylindrical passage, the plunger slidable with respect to the rectangular shaped fluid passage to permit one to increase or decrease the area for fluid to flow through the fluid passage, the stepped plunger having an enlarged portion to prevent the stepped plunger from being accidentally withdrawn from the housing and a flow control knob having threads for rotationally engaging the housing and a shoulder for engaging the stepped plunger so that rotation of the flow control knob on the housing axially displaces the plunger to increase or decrease the area for fluid to flow through the housing to thereby control the flow rate of fluid through the fluid valve in accordance with the rotation of the flow control knob. The flow control valve disassemble for cleaning and having vent passage to prevent accidental injury to a person as the valve is disassembled for cleaning.
