suitable Medium: 150 water, steam, oil products
Product Description: AMERICAN STANDARD BELLOWS GLOBE VALVE (WJ41H)
Product Features & Applications
- Purpose:
- Designed for zero-leakage shut-off and precise flow control in critical industrial processes.
- Ideal for toxic, corrosive, or high-purity media where fugitive emissions must be eliminated (e.g., chemical reactors, LNG plants, pharmaceutical lines).
- Key Features:
- Bellows Seal Design: Hermetically seals the valve stem, preventing external leakage.
- ASME Compliance: Meets API 600, ASME B16.34, and ANSI B16.10 standards.
- High-Temperature Resilience: Operational from -29°C to 425°C (-20°F to 800°F).
- Low-Torque Operation: Smooth quarter-turn or rising stem action for frequent cycling.
