Announcing the launch of our premium Bayonet Valves designed to bring speed, safety, and strength to your operations. Crafted with innovative locking technology and high-grade materials, these valves offer quick, reliable connections and exceptional resistance to wear and tear. Designed to meet the highest standards of industrial fluid control, these valves ensure secure, leak-proof performance even in the most challenging conditions.

Bayonet Valves: Overview and Applications

Introduction

Bayonet valves are specialized angle or lift-type valves engineered to control abrasive, corrosive, and high-temperature slurries. Their signature feature—a bayonet-style stem and seat assembly—delivers extremely tight shut-off and exceptional resistance to erosion and particulate wear. You’ll find these rugged valves in processing plants, mining operations, power stations, and alumina refineries, wherever thick, particle-laden fluids demand uncompromising reliability.

Core Design Principles

Bayonet Stem and Seat Arrangement
  • The stem features a stepped, double-seating bayonet profile that minimizes slurry impingement on critical seals.
  • Two contact faces (primary and secondary) guard against leakage even as the first seat begins to wear.
Robust Body Construction
  • Oversized wall thickness and reinforced bonnet deliver high mechanical strength under pressure fluctuations.
  • Fire-safe trims and metal-to-metal seating ensure functionality during and after external fire exposure.

Technical Specifications

Materials of Construction
  • Carbon Steel (ASTM A216 WCB) : Cost-effective for moderately abrasive slurries.
  • Stainless Alloys (ASTM A351 CF8M/316L) : Enhanced corrosion resistance in acidic or chlorinated media.
  • High-Nickel Alloys (UNS N08031/N08020) : Withstand extreme corrosion in caustic, high-temperature environments.
  • Ceramic Linings/Coatings : Ceramic or rubber-ceramic hybrid linings extend life in highly abrasive services.
Size and Pressure Ratings
  • Size Range : 2″–48″ (DN50–DN1200) to accommodate everything from pilot feeds to main slurry lines.
  • Pressure Classes : Class 150 through Class 1500, with some designs rated up to 900 psi (≈62 bar).
End Connections
  • Flanged Ends : ASME B16.5 RF/RTJ or BS10 standards for leak-tight bolted joints.
  • Threaded Connections : ASME B16.25 or ISO 7/1 for smaller valves and process sampling taps.
Actuation Options
  • Manual : Hand wheel, bevel-gear or spur-gear operators for on-site adjustments.
  • Pneumatic/Hydraulic : Fast response and high thrust for remote or high-cycle applications.
  • Electric : Integration with DCS/PLC for full process automation and feedback monitoring.

Typical Industries and Applications

  • Mineral Processing : Tailings, ore slurries, and concentrate piping.
  • Alumina Refining : Caustic leach streams with high solids loading.
  • Power Generation : Ash handling, flue gas desulfurization slurries.
  • Chemical Processing : Corrosive catalyst slurries in sulfuric acid regeneration.
