API 6A Hydraulic Choke Valve

Product Description

The adjustable and positive choke valves are designed for reliable flow control and maximum wear life, The choke valves are available in flanged or threaded ends in standard bore sizes form 1-13/16" thru 13-5/8",in working pressures of 2000 psi through
20000 psi.
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 20000psi. Choke valves can be
classified as follows: adjustable choke valves and
positive choke valves. By rotating hand wheel to move
the sem. 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 adopter are fabricated from
special carbide allays for corrosion and abrasion
resistance.
Indicator lens with scale marks allows the operator
to know stems position and actual orifice area.
Turn hand wheel counter-clockwise and the valve
will open: turn hand wheel clockwise and the valve
will close.

Fluid
Adjustable choke valve
Valve needle and spool are made of tungsten
Carbide, with sufficient corrosion resistant, anti-
eroding and wearable capacity.
The two kinds of adjustable choke, needle type
and external 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
It adopts union bonnet so as to change choke
quickly.
It has application in wellhead & X-mas tree and
choke line.
