In-line flow limiter (slip-in cartridge) prevents free fall if there is a line failure while allowing a metered flow after closing. A flow below the specified limit is allowed from port 1 to port 2 while a flow above the limit is treated as a line failure and the flow is limited to a bleed rate after closing of 2.0 – 3.0 gpm at 3500 PSI. Flow from port 2 to port 1 passes through the controlling orifice but is uncontrolled.
