3 1/8'' 5K FC Manual Gate Valve

3 1/8" 5K FC Manual Gate valve – High-Pressure Wellhead Equipment for  Petroleum Industry

This robust Manual Gate Valve, engineered with a nominal diameter of 3 1/8 inches (79 mm) and a maximum pressure rating of 5000 PSI, delivers reliable performance in demanding industrial environments. Designed for precise flow interruption and controlled media passage, it is an essential component in systems where safety, durability, and operational accuracy are critical. Built from premium-grade materials such as carbon steel or stainless steel variants, this valve resists corrosion, withstands extreme temperatures, and ensures long-term integrity even under continuous high-pressure conditions.

Key features include exceptional sealing capabilities using advanced seat designs, smooth manual actuation for easy operation without external power sources, and a compact footprint ideal for installations in tight spaces. The valve’s precision-machined components minimize wear, reduce maintenance needs, and enhance overall system efficiency. Its modular construction supports straightforward repair and replacement of internal parts, making it a cost-effective choice over the lifecycle of the equipment.

Engineered for versatility, this manual gate valve handles a wide range of fluids including water, crude oil, natural gas, chemical solutions, and other non-corrosive media. Whether used in upstream oil and gas operations, chemical processing plants, petrochemical refineries, or high-pressure hydraulic systems, it provides consistent on/off control with minimal leakage risk. It meets international standards for pressure vessel components and is suitable for both new installations and retrofits in aging infrastructure.

Industrial users consistently praise its reliability under harsh conditions—particularly in offshore platforms, pipeline networks, and manufacturing facilities where downtime must be minimized. Operators appreciate the intuitive handwheel design that allows for quick shut-off during emergencies, while engineers value the predictable torque requirements and low-stress operation across repeated cycles.

Common questions often center around compatibility with different Pipe, expected service life under varying pressures, and recommended maintenance intervals. While specific parameters depend on application context, general guidelines suggest inspecting seals annually and lubricating moving parts every 6–12 months to maintain optimal function. For optimal results, always match the valve's material grade to the fluid being handled—especially when dealing with aggressive chemicals or elevated temperatures.

As part of a broader portfolio of industrial valves, this 3 1/8'' 5K FC Type Manual Gate Valve stands out as a dependable solution for any facility requiring durable, manually operated control valves in high-pressure scenarios. Ideal for engineers, procurement specialists, and maintenance teams seeking a balance between performance, longevity, and ease of use in global industrial markets.
