API 6A Choke Valve

1.ADJUSTABLE CHOKE VALVE Designed as per API 6A,16C,NACE MR0175;Structure type:needle, cage;Needle, core, seat of Adjustable Needle Choke Valve are all made of carbide alloy for erosion and corrosion resistance, and with reliable performance;Adjustable Cage Choke Valves, based on the principle of “hydraulic energy consumption”, combining with aerodynamics and finite element analysis methods, use the Pistons moving in the opening-hole cage to produce different open area to control flow and pressure. High-pressure liquid flows from choke valves into annular space created between cage and valve body, changes direction and mutually impacts into center of cage to consume liquid own energy, which will consume fluid destruction energy and reduce erosion and noise caused by liquid impacting on choke valve and backward position components, to achieve best utility effects.Driving mode: Manual, hydraulic.Working pressure:3000Psi,5000 Psi,10000 Psi,15000 Psi,20000 PsiNominal bore:2 1/16″, 2 9/16″, 3 1/16″, 3 1/8″, 4 1/16″2.POSITIVE CHOKE VALVE Designed as per API 16A, API 16C, NACE MR0175;Mostly used for Christmas tree, accomplishing flowrate control by changing flow beans of different diameters;The flow bean is fabricated from carbide alloy for erosion and corrosion resistance, and with reliable performance;The stem union connection allows fast make-up and break-out;Working pressure:3000Psi,5000 Psi,10000 Psi,15000 Psi,20000 Psi;Nominal bore: 2 1/16″, 2 9/16″, 3 1/16″, 3 1/8″, 4 1/16″
