ABSTRACT:
A flow control valve having a controllable flow area which varies with the valve displacement. The flow control valve includes a poppet-type valve element mounted to reciprocate between a closed and open position in a valve cavity formed in a valve housing. The valve housing has an inlet and outlet passage to allow fluid to flow therethrough. A removable insert having a flow passage is positioned in the valve cavity adjacent the poppet-valve for controlling the flow rate of gaseous fluid from the inlet passage to the outlet passage while the poppet valve is in an open position. Movement of the poppet valve from a closed to an open position varies the effective cross-sectional flow area of the flow passage.
