3" x 3" Plug Valve Hard Kit (S-Type) | 15,000 PSI High-Pressure Replacement Internals

 The 3" x 3" Plug Valve Hard Kit (S-Type) is a premium, heavy-duty internal rebuild package engineered to restore worn, washed-out, or compromised 3-inch high-pressure plug valves to their original factory performance. Designed for S-type valve architectures, this kit is built to handle the intense abrasion and extreme pressure cycles inherent in hydraulic fracturing, severe-service flowback, and large-scale well-testing operations. Rated for up to 15,000 PSI Cold Working Pressure (15M CWP), this kit ensures your vital high-capacity flow control assets are rehabilitated to maintain safe energy containment and reliable pressure isolation.

The core advantage of this Hard Kit lies in its precision-machined metallic wear components. In a 3-inch full-bore valve, the internal plug and side segments are subjected to massive fluid forces and high-velocity proppant impact. This kit provides direct, exact-match replacements for these critical wear parts. It includes a precision-ground, hardened alloy steel cylindrical plug with a true 3-inch bore, paired with matching high-strength metal side segments (inserts). Manufactured to precise S-type dimensional tolerances, these components ensure a perfect internal fit that restores the smooth, easy actuation and bubble-tight shutoff required in high-pressure 15M systems.

By keeping these S-style hard kits in your maintenance inventory, field technicians can perform complete, on-site valve rehabilitations in minutes. This entirely eliminates the need to scrap expensive, forged 3-inch valve bodies or suffer the long lead times associated with factory refurbishments, extending the operational lifespan of your high-rate frac and choke manifold valves efficiently and cost-effectively.

(Note: As an internal rebuild kit, this product contains the metallic plug and side segments designed to fit inside a 3-inch valve body; the kit itself does not feature external hammer union threads.)

Features & Benefits

• 15,000 PSI Pressure Rating (15M): Components are engineered and machined to safely contain extreme upstream pressures up to 15,000 PSI when installed in a certified 3-inch valve body.

• S-Type Compatibility: Manufactured to exact dimensional specifications for seamless drop-in replacement within S-style 3-inch plug valve architectures.

• Full 3-Inch Bore Configuration: The plug and segments feature a true 3-inch internal bore to maintain maximum flow rates and minimize destructive fluid turbulence.

• Restores Smooth Operation: Replacing scored or pitted internal metal components eliminates binding, restoring the effortless actuation required for safe manual or automated operation.

• Premium Hardened Alloys: The replacement plug and side segments are machined from high-strength, treated alloy steel for maximum resistance against proppant erosion and fluid wash-out.

• Rapid Field Maintenance: Allows rig crews and maintenance techs to completely rebuild a compromised 3-inch valve directly on the well pad, minimizing costly downtime.

Specifications & Technical Details

Applications

This S-style full-bore hard kit is an essential maintenance item for operations utilizing 3-inch heavy-duty plug valves. It is perfectly suited for on-site refurbishments of primary master and wing valves on high-rate frac manifolds, preventative maintenance routines for large-bore choke-and-kill assemblies, and restoring compromised isolation valves in large-scale well-testing layouts.

Quality Assurance

Each hard kit component undergoes strict quality control to guarantee reliable field performance. The plugs and segments are subjected to rigorous dimensional checks to ensure exact S-style fitment, surface finish inspections to guarantee proper sealing surfaces, and hardness testing to verify the material's resistance to extreme abrasive wear.
