Choke Valve

Adjustable Choke Valve, Positive Choke Valve, Orifice Choke Valve, Hydraulic Drilling Choke Valve, Plug and Cage Choke Valve, External Sleeve Choke Valve.

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 stem’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.

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

·It adopts union bonnet so as to change choke quickly.

·It has application in wellhead& X-mas tree and choke line.

·Material of choke bean is fabricated from ceramic and tungsten carbide, with sufficient corrosion resistant, anti-eroding and wearable capability.

The KERGY class 900# (2,025 psi) and 1,500# (3,375 psi) drilling chokes are the most widely used and respected well-killing and high-pressure-control drilling chokes in the industry. For more than 35 years, these chokes have been especially effective when used during well kicks, well testing and well cleanup operations. They are designed and manufactured for H2S and abrasive-fluid applications and in accordance with API and NACE standards.

High-pressure drilling chokes. Built to handle class 900# to 1,500# (2,025 psi to 3,375 psi), SANYI chokes are precision engineered for precise well control. Unique choke-plate design. Heavy-duty, diamond-lapped tungsten-carbide plates are honed to a flatness measured by lightbands and feature unique half-moon-shaped orifices. Rotation of the actuator fork allows finite regulation of the size of the opening from full open to full close. Positive closure. A 17° deadband overlap beyond the full-close position is designed to ensure closure even if the plates become worn following extended exposure to abrasive-laden fluid flow. Pressure drops or surges don’t affect the quality of the seal in the plate-to-plate design. In fact, the seal improves under pressure. Tungsten-carbide wear sleeves. Hardfacing on wear sleeves increases in-service life. Extended wear sleeves are available to absorb effects of abrasive downstream turbulence, especially during underbalanced drilling operations. Versatile. Ideal for onshore and offshore applications. Controls can be operated from either remote or onsite consoles.
