MANUAL CHOKE VALVE

The choke valve is designed to control production rate of the oil well, with working pressure up to 10000psi. Choke valves can be classified as follows: adjustable choke valves and positive choke valves. By rotating hand wheel to drive 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:
1. The coupling nut used for connecting the bonnet and body allows fast make-up and break-out.
2. Stem tip and bean adaptor are fabricated from special carbide alloys for corrosion and abrasion resistance.
3. Indicator lens with scale marks allows the operator to know stem’s position and actual orifice area.

4. Turn hand wheel counter-clockwise and the valve will open; turn hand wheel clockwise and the valve will close.

 HYDRAULIC CHOKE VALVE

The hydraulic choke valve is used to be matched with manifold and other assemblies, which is applicable for flow-rate adjustment, that is, to raise or reduce the valve core location is help for alternation of flow-way cross-area and flow-rate control.

DFF STYLE CHECK VALVE
The product is designed and manufactured according to API Spec 6A “Equipment Specification of Wellhead & X’mas tree” and matched and interchangeable with any equipment which conforms to API 6A specification.
It creates the metal-to-metal seal by the pressure of the medium, the more the pressure is, the better the sealing effect is. Anytime the valve chamber can bear the pressure of the pipeline.
Valve body is machined of alloy steel forging with a stronger machinery properties and reliable performance.
Bonnet is connected with valve body with bolt, the seals include the sealing ring in the bonnet and the seal in the valve body;
The sealing face between valve core and valve body is welded with hard alloy with good abrasion resistance and anti-scour; the valve core is made of sulfide-resistance steel and the others adopt the process of hardness limit so the valve is able to be used in H2S condition.
The sealing-face of the valve core and the valve body is bead-welded with carbide, plus rubber seals, which has
