API 6a Adjustable Chokes

Adjustable chokes are made of modern materials and via Modern manufacturing techniques.They are robust, easy to maintain, fully conforms to API Spec.6A.Reasonable price and low cost of spares make them the most cost effective chokes on the market. Adjustable chokes can be divided into needle, plunger and orifice plate type and can be manually or hydraulically operated.Flow and pressure can be adjusted through changing fluid passage section by cone surface of needle, vertical movement of plunger or rotation of orifice plate Features Manufactured and tested in accordance with API 6A. Carbide alloy is embedded into cone head of valve, flow nipple, plunger and orifice plate. Flow adjustment is indicated on a measuring scale. Both thrust bearings with large load capacity and composite rubber-plastic stem lip packing reduces operating torque Available Medium:Oil, gas, slurry and sour gas Rated Working Pressure:2, 000psi ~ 20, 000psi Bore Size:All popular Temperature:K ~ U Material Classes:BB ~ HH End connections:Flange, union Product Specification Level:PSL1 ~ PSL4 Performance Requirement:PR1, PR2
