Anti Corrosion Manual Gate Valve 3 1/8" 5000psi API 6A Standard

Product Overview

1. The API 6A manual slab gate valve is designed for reliable shutoff and flow control in oil and gas wellhead applications. With a 3 1/8" bore size and 5000psi pressure rating, it is widely used in tubing heads, casing heads, manifolds, and Christmas tree systems. The valve is available in both rising stem and non-rising stem designs, ensuring flexibility for different installation requirements. The sealing surfaces are treated with tungsten carbide hard facing or QPQ nitriding for superior wear resistance and corrosion protection, making it ideal for long-term service in harsh environments.
