Angle bellows stop valve

Our angle bellows globe valve combines the superior throttling capability of globe valves with the leak-proof reliability of bellows seals in a compact 90° design. Engineered for critical process applications, it delivers bubble-tight shutoff while optimizing flow dynamics in space-constrained installations.

Product Overview

Our angle bellows globe valve combines the superior throttling capability of globe valves with the leak-proof reliability of bellows seals in a compact 90° design. Engineered for critical process applications, it delivers bubble-tight shutoff while optimizing flow dynamics in space-constrained installations.

Key Features

1. Advanced Sealing Technology

  • Dual-layer 316L/INCONEL bellows (10,000+ cycle life)
  • Secondary graphite packing as backup seal
  • 100% helium leak tested per ISO 15848-1 Class AH

2. Optimized Flow Design

  • Angled body configuration reduces pressure drop by 30% vs standard globe valves
  • Parabolic plug profile for precise Cv characteristics
  • Equal percentage flow curve (±2% accuracy)

3. Rugged Construction

  • Forged ASTM A105/A182 F316 body
  • Integral bonnet design eliminates gasket leakage points
  • Stellite 6 hard-faced seat and plug (HRC 40-45)
