The High-Pressure Cartridge Grease Box Plug Valve is a premium, heavy-duty flow control solution engineered for the most abrasive and demanding oilfield environments. Designed specifically for high-pressure cementing, fracturing, and flowback operations, this quarter-turn valve features an innovative internal cartridge design paired with an advanced continuous-lubrication grease box system.

The proprietary "cartridge" assembly contains the plug, side segments, and elastomer seals in a single, self-contained unit. This allows for rapid, inline maintenance without removing the valve body from the manifold. The integrated "grease box" acts as a pressurized lubrication reservoir, continuously forcing heavy-duty grease into the sealing interfaces. This flushes out abrasive frac sand, reduces operating torque, prevents galling, and significantly extends the service life of the valve internals compared to standard non-lubricated designs.

Manufactured from high-strength forged alloy steel, this plug valve is built to handle massive fluid volumes, severe pressure surges, and highly abrasive slurries. Available with standard Figure 1502 hammer union connections (or customized end configurations), it provides blowout-proof reliability in 15,000 PSI continuous service applications.

Features & Benefits

  • Advanced Grease Box System: Features an integrated grease reservoir that continuously lubricates the plug and seal interfaces, flushing out abrasives and drastically increasing internal component lifespan.

  • Rapid Inline Maintenance: The internal cartridge design allows field operators to pull and replace the entire internal sealing assembly as a single unit without removing the valve body from the iron string, reducing costly downtime.

  • Low Operating Torque: The constant lubrication provided by the grease box, combined with precision-machined internal segments, ensures the valve can be easily actuated under extreme pressure without sticking or binding.

  • Integral Forged Body: The valve body is machined from a single solid block of premium alloy steel, eliminating weak points and providing maximum resistance to high-pressure fracturing surges and vibration.

  • Visual Position Indicator: Equipped with a clearly marked open/close indication cap or handle assembly for instant visual confirmation of flow status on busy well pads.

Applications

This Cartridge Grease Box Plug Valve is essential for operations dealing with highly abrasive fluids and high-pressure differentials. It is the preferred flow control valve for frac iron manifolds, flowback packages, heavy-duty cementing lines, acidizing manifolds, and sand separator systems where standard valves would quickly degrade or seize.

Quality Assurance

Every plug valve is subjected to rigorous testing and quality control. Forged bodies are ultrasonically inspected for structural integrity. Each fully assembled valve undergoes strict hydrostatic pressure testing (up to 22,500 PSI for a 15k rated valve) to verify seat sealing and body integrity. Actuation torque is measured under pressure to ensure smooth operation in the field.
