Super Choke Valve (Manual & Hydraulic Actuator)

The super choke valves 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.

 The super manual & hydraulic actuator choke valve is molded of two pieces of special carbon tungsten plates with rather ability of erosion resistance, one of which rotates to alter the concentricity between the upper orifice and lower orifice of two plates so as to adjust the flow-rate of fluid or gas.

 The valve is used for manifold such as drilling, fracture, mud circuit, ground high-pressure gas injection/production, it has a outstanding feature that the pressure difference between inlet and outlet, as closing, can press both of the plates fast together so as to put into effect of sealing cutting, especially in the case that the pressure suddenly rises or falls, the pre-set sign-rate of high/low pressure sensor can be helpful for automatic closing/shut so as to avoid heavy accident. It is outstanding advantage that it has long working life and ability of erosion/corrosion resistance in comparing with other choke valves.

Functional Specification

High-pressure drilling chokes. Built to handle class 900# to 1,500# (2,025 psi to 3,375 psi) ,Super choke valves 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 light bands 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.
