Product Detail

The Devlon Soft-Seated Reduced-Bore Trunnion Ball Valve with NACE Standard is a heavy-duty, high-performance isolation solution engineered specifically for sour oil and gas transmission pipelines and severe industrial processing. Designed in full compliance with NACE MR0175 / ISO 15156 standards, this valve utilizes carefully selected sour-service forged materials and controlled hardness limits to resist sulfide stress cracking (SSC) in $\text{H}_2\text{S}$-laden environments. Featuring a robust trunnion-mounted fixed-ball architecture, it ensures stable operation and low torque under high pressure differentials. The high-performance Devlon seat inserts provide exceptional wear resistance, high mechanical strength, and superior resistance to cold flow compared to standard PTFE, guaranteeing a reliable bubble-tight shut-off in a cost-effective reduced-bore design.

Design Description

NACE MR0175 / ISO 15156 Compliance: Manufactured using sour-service-certified materials and strict hardness control ($\le 22\text{ HRC}$), ensuring safety and longevity in corrosive sour gas fields.
High-Performance Devlon Seat Inserts: Devlon provides superior compressive strength, lower friction, and excellent resistance to deformation under high pressure, outperforming standard soft-seat materials.
Trunnion-Mounted Stability: Fixed-ball design absorbs high line thrusts, maintaining low and predictable operating torques across high-pressure ratings.
Reduced-Bore (Venturi) Economy: Optimized flow path design offers a lighter footprint and cost-saving advantages for piping networks where full-bore pigging is not required.
