Design Description

One-Piece High-Pressure Body: The unibody forged construction eliminates central flange joints, minimizing leakage paths under high-pressure conditions.
Low-Temperature Toughness: ASTM A350 LF2 material is Charpy impact tested to ensure no brittle fracture in freezing climates.
Rapid Pneumatic Response: Equipped with piston or scotch-yoke actuators, supporting fail-safe options (Fail-Close/Fail-Open) with fast, stable operation.
Double Block and Bleed (DBB): Fully compliant with API 6D, utilizing spring-energized seats for independent bi-directional sealing and safe cavity venting.
Comprehensive Safety Suite: Features fire-safe design (API 607), anti-static devices, and anti-blowout stems for maximum security in hazardous services.
ISO 5211 Direct Mounting: Features a standardized top-mounting pad for seamless integration of pneumatic actuators, limit switches, and solenoid valves.
