3-1/16" 15K (15M) Manual Operated FC Type Gate Valve – Oil & Gas Flowline Valve

The 3-1/16" 15K Manual Operated FC Type Gate Valve is a premium, extreme-duty flow control valve engineered for the absolute safe isolation and regulation of ultra-high-pressure fluids in severe upstream oil and gas operations. Rated for an immense cold working pressure of 15,000 PSI (15K / 15M), this manual gate valve features a full-bore 3-1/16" opening to provide unrestricted flow, effectively eliminating turbulence and minimizing pressure drops across critical wellhead and manifold systems.

Based on the industry-proven "FC" style design, this valve features a highly reliable slab gate and a true metal-to-metal sealing mechanism (gate-to-seat and seat-to-body), ensuring bi-directional pressure containment and exceptional resistance to abrasive fluids. The robust forged alloy steel body and bonnet are designed to withstand the violent internal stresses of extreme-pressure frac operations, heavy well testing, and severe choke-and-kill applications.

Operated via a heavy-duty manual handwheel, the valve incorporates a non-rising stem design with high-quality thrust bearings, reducing operating torque and allowing operators to safely open and close the valve even under massive pressure differentials. Fully compliant with API 6A standards, this FC type gate valve guarantees reliable field interchangeability, straightforward inline maintenance, and uncompromising pressure containment in the harshest operational environments.

Features & Benefits

• Ultra-High-Pressure Containment: Engineered to safely manage extreme upstream environments with a 15,000 PSI (15K) working pressure rating.

• Proven FC Type Design: Fully interchangeable with standard "FC" style components, ensuring widespread industry familiarity and easy sourcing of replacement parts.

• Metal-to-Metal Sealing: Utilizes specialized metal-to-metal seals between the gate and seat, as well as the seat and body, providing a superior, highly durable barrier against abrasive frac sand and high-velocity fluids.

• Low Operating Torque: Features a non-rising stem combined with heavy-duty thrust bearings, ensuring smooth and manageable manual operation under full working pressure.

• Bi-Directional Flow: The floating slab gate design allows the valve to effectively seal pressure from either direction, maximizing installation flexibility and system safety.

• Forged Alloy Steel Construction: Delivers exceptional structural integrity, effectively resisting severe mechanical impacts, thermal shock, and aggressive corrosion.

Specifications & Technical Details

Applications

This 3-1/16" 15K manual FC type gate valve is a critical structural hub for extreme-pressure upstream fluid control. Typical applications include serving as master or swab valves on heavy-duty wellhead and frac trees, isolating flow on choke and kill manifolds, regulating flowback procedures, and safely containing ultra-high-pressure environments in surface well testing networks.

Quality Assurance

Each FC type gate valve undergoes the most stringent quality control protocols, including severe hydrostatic body and seat testing, complete dimensional verification, precision seal inspection, and full material traceability (MTRs), ensuring strict compliance with API 6A and API Q1 standards for dependable, safe field performance.
