3" x 3" 1502 Plug Valve Pneumatic Actuated (ESD) | 15K PSI Sour Service NACE | Oilfield Valve

3" x 3" 1502 Pneumatic Actuated Plug Valve (ESD) – 15K PSI Sour Service

Engineered for high-pressure oilfield operations, this 3" x 3" 1502 pneumatic actuated plug valve with ESD delivers reliable shut-off performance in 15,000 PSI (15K) environments. Designed specifically for sour gas (H2S) applications, it is fully compliant with NACE MR0175 / ISO 15156, ensuring long-term resistance to corrosion and sulfide stress cracking.

The integrated Emergency Shut-Down (ESD) system combined with a fail-safe pneumatic actuator enables rapid and automatic valve closure during critical situations—making it ideal for safety-critical operations in oil & gas fields.

Built with forged alloy steel construction, this valve ensures durability, minimal maintenance, and consistent performance in the harshest field conditions.
