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

Product Overview

1. The Flat Hydraulic Gate Valve, 3 1/8" 5000psi, is designed and manufactured in compliance with API 6A standards, ensuring reliable performance in critical oil and gas applications. Widely used in wellhead assemblies, Christmas trees, tubing heads, casing heads, and manifolds, this valve provides safe and efficient isolation of production fluids.
2. Built with an anti-corrosion design, the valve body and trim are treated with advanced surface hardening technologies such as tungsten carbide overlay and QPQ treatment, enhancing wear resistance and extending service life under severe working conditions. Hydraulic actuation enables fast and remote operation, improving safety and reducing manual intervention in high-pressure operations.
3. Before delivery, each valve undergoes strict hydrostatic and sealing tests in accordance with API 6A, ensuring full compliance with performance and safety requirements.

Key Features
