ARI – REYCO® R & RL Full-Nozzle Safety Relief Valves

Reyco R Features & Benefits

• Legacy Compatibility: Fully interchangeable with legacy Lonergan D, DB, LCT 14, LCT 40 series — simplifies retrofit and maintenance.
• Single Trim for All Services: Eliminates need for separate configurations per medium (e.g., steam, gas, liquid).
• Reversible Disc: Built-in spare part improves cost efficiency and service continuity.
• Unified Nozzle Ring per Orifice: Reduces parts variation and simplifies inventory management.
• Standard Bellows (Inconel® 625 LCF): NACE MR0175/0103 compliance with superior corrosion resistance — no upgrades needed.
• Notched Bearing Points: 140° notch design ensures disc concentricity, enhancing sealing and stability.
• Soft Seat Option: Direct spring loading on metal seat maximizes O-ring life and reduces maintenance costs.
• Corrosion-Free Disc Retention: Ring-based disc retention avoids thread corrosion and removes need for special tools.
• Top-Threaded Nozzle: Improves nozzle-to-body alignment, prevents cavity seepage, and enhances tightness beyond API 527 standards.
• Split-Spindle Design: Improves alignment and sealing compared to older one-piece stems used by competitors.
• Valve Position Indicator (VPI): Provides remote indication when valve lifts — ideal for critical or inaccessible installations.

Reyco RL Features & Benefits

• Single Trim for All Services: Simplifies inventory and ordering—provides full capacity at 10% overpressure across liquid, steam, and vapor applications.
• Precision Lapped Seats: Offers tight shutoff performance—exceeds API 527 leakage standards with either metal or soft seat configurations.
• Material Flexibility: Available in CS, SS, Monel®, Hastelloy® C, Duplex, and Alloy 20—suitable for corrosive, H₂S, cryogenic, and various fluid services.
• Certified to ASME XIII (formerly ASME VIII): Ensures code compliance and performance validation via the National Board.
• Simplified Design (RL14): Only 14 parts—supports easier field service and lower maintenance costs.
• Parts Commonality: RL40 and RL41 models share components with REYCO® R and RB Series—reduces spare part requirements.
