    Most Common Choke Valves: •Positive: –Fixed orifice. –Disassemble to change bean. •Adjustable: –Provides variable orifice size through external adjustment. A choke is a restriction in a flow line that causes a pressure drop or reduces the rate of flow. It commonly uses a partially blocked orifice or flow path. Variable Chokes – good for bringing wells on gradually and optimizing natural gas lift flow in some cases. Prone to washouts from high velocity, particles, droplets. Solutions – hardened chokes (carbide components), chokes in series, dual chokes on the well head. Beans are fixed (non adjustable) orifices – ID size is in 64ths of an inch.
