Valve needle and spool are made of tungsten carbide, with sufficient corrosion resistant, anti-eroding an wearable capacity.
The two kinds of adjustable and external sleeve type could apply to wellheads&X-mass tree and choke manifold.
Features:
The coupling nut used for connecting the bonnet and body allows fast make-up and break-out;
Stem tip and bean adapter 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;
