Forged Steel Self-sealing Butt Welding Gate Valve

Premium forged steel self-sealing gate valves with butt weld ends (ASME B16.25) deliver unmatched sealing performance through innovative pressure-activated technology. Designed for critical isolation applications, these valves automatically enhance sealing force as system pressure increases, ensuring zero-leakage performance in the most demanding oil & gas, petrochemical, and power generation systems.
