3" x 3" 1502 Gear Operated Plug Valve | Sour Service H2S NACE Oilfield Valve

3" x 3" 1502 Gear Operated Plug Valve – Sour Service H2S Resistant Valve

The 3" x 3" 1502 Gear Operated Plug Valve is designed for reliable flow control in sour service environments where hydrogen sulfide (H2S) and corrosive fluids are present. Built using NACE MR0175 / ISO 15156 compliant materials, this valve provides resistance to sulfide stress cracking, corrosion, and hydrogen embrittlement.

The gear-operated mechanism allows smooth and controlled valve operation with reduced manual effort, making it suitable for high-pressure oilfield applications. Its metal-to-metal sealing system ensures secure shutoff and leak-resistant performance, maintaining system safety and integrity in demanding conditions.

Constructed with high-strength materials and precision engineering, this valve delivers long service life and dependable performance in upstream and midstream oil and gas operations.
