3" x 3" 15,000 PSI Fig 1502 LT Gear Box Actuated Plug Valve – Oil & Gas Flowline Fitting

The 3" x 3" Fig 1502 Gear Box Actuated Plug Valve (Low Temperature) is engineered for absolute flow isolation and dependable pressure control in the most demanding, extreme-cold upstream oil and gas environments. Rated for a 15,000 PSI cold working pressure, this heavy-duty flowline valve incorporates a high-efficiency gear box actuator. This critical feature provides mechanical advantage, significantly reducing the operating torque required by personnel to open or close the 3-inch bore under massive internal pressure loads, thereby enhancing operational safety and efficiency.

Manufactured from premium, specially heat-treated forged alloy steel, this valve is strictly rated for Low Temperature (LT) service. It is designed to maintain structural integrity, impact resistance, and reliable sealing performance in sub-zero field conditions where standard materials may become brittle. The standard 3-inch Figure 1502 hammer union ends ensure rapid, secure integration into high-volume temporary flowlines and manifold systems.

With its rugged construction, low-torque operation, and specialized cold-weather materials, this gear-operated plug valve is a trusted, field-ready solution for high-capacity fluid control across harsh-environment frac, well testing, and production operations.

Features & Benefits

• Gear Box Actuator: High-efficiency gear reduction mechanism allows for smooth, low-torque operation under extreme 15,000 PSI pressure loads, reducing operator fatigue.

• Low Temperature (LT) Rated: Constructed from specialized forged alloy steel to maintain toughness, impact resistance, and sealing integrity in extreme cold-weather and arctic conditions.

• 15,000 PSI Rating (15M): Engineered to safely contain ultra-high-pressure upstream environments, perfectly matched to 1502 iron ratings.

• High-Volume 3-Inch Bore: Accommodates high fluid flow rates typical of heavy-duty pumping and flow-back operations.

• Figure 1502 Union Ends: Industry-standard hammer union connections ensure fast, ultra-secure rig-up and tear-down in the field.

• Low Maintenance Design: Built for straightforward field service with easily replaceable internal plug and seal components to minimize rig downtime.

Specifications & Technical Details

Applications

This LT gear-actuated plug valve is essential for high-volume, extreme high-pressure upstream operations situated in cold-weather climates. Typical applications include high-capacity frac manifolds, severe winter surface well testing flowlines, high-pressure pump discharge lines, and heavy-duty flow-back operations requiring reliable, low-torque flow isolation without the risk of low-temperature material embrittlement.

Quality Assurance

Each gear-operated plug valve undergoes rigorous quality inspection protocols, including severe hydrostatic shell and seat testing, torque testing of the gear mechanism, and strict material traceability verification to ensure reliable, fail-safe performance in extreme cold and high-pressure field conditions.
