2-inch Plug Valve Insert

Crafted from high-strength 4140 alloy steel, this 2-inch plug valve insert is optimized for rapid opening/closing in fracturing manifolds. Through advanced heat treatment, its surface hardness exceeds 40 HRC, allowing it to withstand the abrasive grit of high-concentration proppants used in shale gas fracturing. The insert features a self-lubricating coating to reduce torque and extend seal life. Its hammer-union design allows for fast field maintenance, serving as a standard consumable in high-intensity stimulation operations.
