3" Figure 1502 Adjustable Choke Handwheel – High-Pressure Valve Operator

The 3" Figure 1502 Adjustable Choke Handwheel is a heavy-duty manual override component designed for the precise operation of high-pressure adjustable choke valves. Engineered to provide the necessary leverage for controlling flow in extreme-service environments, this handwheel is a critical interface for operators managing well-testing, flowback, and manifold systems rated up to 15,000 PSI (15K).

Constructed from high-strength cast or forged steel, the handwheel is built to withstand the rigorous mechanical stress and environmental exposure common in oilfield operations. It features an ergonomic, large-diameter design that allows for smooth, incremental adjustments of the choke stem, enabling fine-tuned regulation of line pressure and flow rates. The hub is precision-machined to ensure a secure, slip-free fit onto the choke stem or gearbox input shaft, preventing backlash and ensuring immediate valve response.

Designed for long-term field durability, this handwheel is often coated with high-visibility, corrosion-resistant finishes to ensure ease of use and safety in low-light or harsh weather conditions.

Features & Benefits

• High-Leverage Design: Large diameter provides the mechanical advantage required to actuate high-pressure choke stems under full operational load.

• Precision Control: Enables minute adjustments to the choke orifice, allowing for accurate pressure management and flow stabilization.

• Heavy-Duty Construction: Built from impact-resistant steel to handle the vibration and mechanical abuse of the "frac" site or production pad.

• Corrosion Protection: Finished with industrial-grade coatings to resist rust, salt spray, and chemical exposure.

• Universal Fit: Specifically engineered for standard 3" Figure 1502 adjustable choke assemblies, ensuring seamless replacement of OEM handles.

• Safety Markings: Often includes directional arrows (Open/Close) for quick visual confirmation and operational safety.

Specifications & Technical Details

Applications

This 3" handwheel is strictly used for the manual operation of adjustable choke valves within high-pressure flowline systems. Typical applications include managing flow rates on choke and kill manifolds, regulating pressure during well-testing operations, and providing manual control on frac flowback skids where automated actuators are not utilized.

Quality Assurance

Each handwheel is inspected for dimensional accuracy and structural integrity. The casting is verified to be free of defects, ensuring that it will not crack or fail under the high-torque requirements of high-pressure fluid isolation and regulation.
