Axial Choke Valves

Axial Choke Valves

Goodwin choke valves utilize solid tungsten carbide trim, therefore, minimizing the erosion of critical components, thereby providing long-term reliability of performance in severe service. With the use of “torturous path” technology, it dissipates and controls the high energy, velocity, and turbulence within its trim. Consisting of one or more concentric sleeves with specifically aligned holes in each, the trim provides controlled staged pressure reduction.

Actuation Options Include:

• Manual Operation

• Pneumatic

• Hydraulic

• Electric

• Electro-hydraulic

Effective Control of Fluid Velocities Goodwin utilise “torturous path” technology to dissipate and control the high energy, velocity and turbulence within its trim. Consisting of one or more concentric sleeves with specifically aligned holes in each, the trim provides controlled staged pressure reduction.

Superior Wear Resistant Materials of Construction Goodwin Choke Valves utilise solid tungsten carbide trim minimising the erosion of critical components, thereby providing long term reliability of performance in severe service.

Streamlined Axial Flow Path The streamlined flow path through an Axial Choke Valve has minimal pressure drop and the flow is directed through the valve to avoid critical sealing areas promoting longevity of the sealing arrangement.

Large Flow Area Enables easy handling of solids contributing to reliable performance.

Accurate Control Made feasible by the fully pressure balanced design.

High Turndown Extensive rangeability provided by the accurate control and inherent high capacity features of the valve.

Multi-Stage Trims Employing bespoke multi-stage trims designed and manufactured according to each application. Each trim optimised for safe and reliable control of pressure, velocity, erosion, noise and vibration.

Trim Change-Out One choke valve body can accommodate changing wellhead conditions by changing the trim. With its high rangeability trim, the Goodwin Axial Choke Valve could cover from start to end of life well production scenarios.

Rack-Pinion-Rack Gear Train Goodwin Axial Isolation Valves utilise Goodwin’s patented Rack-Pinion-Rack gear train mechanism to transpose the linear motion of the actuator through 90° into axial motion of the piston which provides: High durability, rapid and precise movement. Closure in less than 2 seconds. High rangeability. Zero risk of gear teeth seizure with minimal or no lubrication. Low Friction and high efficiency compared to sliding gear mechanisms. Low backlash maintained over the lifetime of the product.
