3" 15,000 PSI Fig 1502 Adjustable Choke Bonnet Assembly – Oil & Gas Valve Part

The 3" Figure 1502 Adjustable Choke Bonnet Assembly is a complete, pre-built top-works unit engineered for the rapid repair and restoration of high-pressure choke valves. Rated for a Cold Working Pressure (CWP) of 15,000 PSI, this heavy-duty assembly is designed to drop directly into an existing 3" 1502 choke body. It is an indispensable inventory item for well testing, frac flowback, and drilling operations, allowing rig crews to swap out the entire control mechanism in minutes, drastically reducing costly Non-Productive Time (NPT).

This comprehensive assembly comes fully integrated with all critical internal components. It typically includes the heavy-duty forged alloy steel bonnet, a precision-machined stem (often featuring a severe-service tungsten carbide tip for maximum erosion resistance), the complete packing and seal arrangement, the indicator scale, and the handwheel mechanism. By utilizing a pre-assembled unit, operators eliminate the risk of improper field-rebuilding, ensuring that the delicate stem packing and seals are correctly seated and factory-tested prior to installation.

Built to withstand the severe vibration, abrasive slurries, and extreme pressure cycling of modern upstream environments, the 3" 1502 Choke Bonnet Assembly delivers reliable, precise flow regulation and absolute blowout-proof containment.

Features & Benefits

• Complete Drop-In Unit: Fully pre-assembled with the bonnet, stem, packing, indicator, and handwheel for immediate, hassle-free field installation.

• 15,000 PSI CWP Rating: Engineered to safely contain and regulate extreme pressures within 15M choke and kill manifold systems.

• Tungsten Carbide Stem Tip: Provides superior resistance to erosion and wear when throttling abrasive frac sand or high-velocity drilling fluids.

• Premium Factory Seals: Packing and O-rings are pre-installed to exact torque and compression specifications, ensuring a bubble-tight, leak-free seal.

• Reduced Downtime: Eliminates the need to rebuild individual valve internals on the pad, getting critical manifolds back online quickly.

• Standard Interchangeability: Fully compatible with industry-standard 3" Figure 1502 adjustable choke bodies.

Specifications & Technical Details

Applications

This 3" Figure 1502 complete choke bonnet assembly is essential for operations requiring precise flow control and rapid equipment turnaround. Typical applications include servicing choke and kill manifolds on drilling rigs, rebuilding adjustable valves on high-pressure well-testing headers, and maintaining frac flowback skids where abrasive wear necessitates frequent valve replacement.

Quality Assurance

Each bonnet assembly is built and tested under rigorous quality control standards. The complete unit undergoes precise dimensional inspection, and the stem travel is tested for smooth operation. Seal integrity is verified to guarantee blowout-proof performance under maximum 15,000 PSI operational loads.
