3" x 3-1/16" 15M Standard Plug Valve – Oil & Gas Flowline Valve

The 3" x 3-1/16" 15M Standard Plug Valve is a robust, quarter-turn flow control device engineered to provide rapid, bubble-tight shut-off in extreme-pressure upstream oil and gas operations. Rated for an immense cold working pressure of 15,000 PSI (15M), this heavy-duty valve utilizes a standard 3-inch nominal connection profile while maintaining a 3-1/16" internal bore, making it an indispensable asset for high-capacity cementing, fracturing, and severe surface well testing manifolds.

Manufactured from premium high-strength forged alloy steel, this plug valve is built to withstand the violent internal stresses, abrasive slurries, and extreme pressure spikes typical of heavy-duty pumping applications. It features a precision-machined plug that rotates smoothly within a heavily reinforced body, ensuring quick, low-torque quarter-turn actuation for immediate flow diversion or isolation. The robust sealing segments and precision fit provide superior resistance to high-velocity frac sand and aggressive fluids.

Designed with operational efficiency in mind, this standard plug valve incorporates accessible grease fittings for routine field lubrication and a top-entry design to facilitate straightforward inline maintenance. By delivering reliable, repeatable pressure containment, this 15M plug valve serves as a vital safety and control mechanism in complex, high-pressure flowline networks.

Features & Benefits

• Rapid Quarter-Turn Actuation: Allows for immediate opening or closing of the flowline, ensuring rapid response during critical pressure control situations.

• 15,000 PSI Rating (15M): Engineered and strictly tested to safely contain extreme-pressure upstream environments without compromising structural rigidity.

• Premium Forged Steel Construction: Delivers superior strength and exceptional resistance against abrasive frac sand, high-velocity fluids, and severe field impacts.

• Low-Torque Operation: Precision-machined internal components and regular grease injection ports ensure smooth, manageable operation even under massive differential pressures.

• Inline Maintainability: Top-entry design allows for fast, efficient replacement of internal sealing components without completely removing the valve from the manifold.

• Reliable Sealing Integrity: Advanced insert and seal configurations provide dependable, bubble-tight isolation in both directions.
