The choke valve, a main component of Christmas tree, is design to control production rate of the oil well, with working pressure up to 15000psi. Choke valves can be classified as follows: adjustable choke valves and positive choke valves. By rotating hand wheel to move the stem, the adjustable choke valve is designed to adjust the effective area available for the flow to accomplish control of production rate. The positive choke valve is design to accomplish control of production rate by changing flow beans. Features: The coupling nut used for connecting the bonnet and body allows fast make-up and break-out. Stem tip and bean adaptor are fabricated from special carbide alloys for corrosion and abrasion resistance. Indicator lens with scale marks allows the operator to know stemâ??s position and actual orifice area. Turn hand wheel counter-clockwise and the valve will open; turn hand wheel clockwise and the valve will close. Main technical datum Working Pressure: 2,000-20,000psi Nominal Dimension: 2-1/16 ~ 7-1/16 Working Temperature: P U Product Specification Levels: PSL1 ~ 4 Performance Requirement: PR1 ~ 2 material Class: AA ~ FF Working Medium: crude oil; natural gas Adjustable choke valve Valve needle and spool are made of tungsten carbide, with sufficient corrosion resistant, antieroding and wearable capability. The two kinds of adjustable choke, pintle type and the sleeve type could apply to wellheads& X-mas tree and choke manifold. Positive choke valve Material of choke bean is fabricated from ceramic and tungsten carbide, with sufficient corrosion resistant, anti-eroding and wearable capability.

Introduce: The emc standard of frequency range of 150 khz-30mhz on restraining the conducted cm emi are becoming more serious in the application. Cm inductance & filter capacitor were used to restrain the cm emi. Ferrite core or common nano-crystalline core are popular in domestic market as common mode choke cores, but high high-frequency volume and impedance reduction from 150 khz to 30mhz due to the operating frequency limitation makes these cores unworkable. In this ease, nicore developed advanced higher property nano-crystalline common mode choke cores as solution for emc common mode choke cores requirement, and were applied to the emc of switch power modules, ups power supply, communication power supply, inverter, transducer, home appliance. Characteristics: - high initial permeability: 5~20 times higher than ferrite core - high saturate induction density: 2-3 times higher than ferrite core, not easy be saturated in high current fields - excellent temperature stability-with the serving temperature from -55 to 130"c for a long time. The curie temperature is higher. The properties are not changeable easily even in unstable working temperature. - good frequency flexibility-better controlling to the noise in different frequencies. - higher anti-unbalanced-current: specially made nano-crystalline emc common mode choke cores can guarantee 104 permeability when resist 80a/m unbalanced current bias field. Application area: - protection for accurate electronic equipment - common mode jams filtering for emi power - common filtering in single phase or three phase circuit
