Forged from premium alloy steel and heat-treated for maximum hardness, this full-open design provides a larger flow area to reduce fluid velocity and turbulence. The assembly features a high-grade polyurethane insert that maintains a tight seal even with high proppant concentrations. Precision-machined guide wings ensure stable movement and perfect alignment, preventing uneven wear. This valve is critical for maintaining pump efficiency and reducing unplanned downtime in well-service applications.
