Orifice Choke Valve

The orifice choke valve is molded from two pieces of special carbon tungsten plates that are erosion resistant. One of the plates rotate to alter the concentricity between the upper orifice and lower orifice so as to adjust the flow rate of the fluid or gas. The valve has an advantageous long working life and is rosion/corrosion resistant when compared to other choke valves.

Unique Design
The orifice plate is molded from two pieces of special carbon tungsten and is ground by a diamond bruiting wheel. The opening dimensions of orifice plate are regulated by rotating the valve stem.

Positive Closure
A 17°overlap type sealing tape beyond the full-close position was designed to ensure closure. This will protect the sealing in the event of a sudden increase in pressure or abrasion.

Description

Tungsten-Carbide Wear Brushing
The overlay applied to the face of the wear brushing increases the service life and improves the extensibility of wear brushing. This helps to accept abrasive downstream turbulence, especially during unbalanced drilling operations.

Multiple Applications
Both remote control and on-site manual operation are available during onshore and offshore operations.

Features:
■ Built for oil fields;
■ Precision manufacturing;
■ One-way plate to plate design;
■ Wear-resistance tungsten carbide wear bushing increases its service life;
■ Versatile for onshore and offshoreoperations;
■ On-site control or remote
