High Temperature Expansion Valve

Ultra-High Temperature Expansion Valves for Extreme Industrial Applications
(API 6A PSL3G Certified | 650°F Rated | Hard-Alloy Reinforced Seals)

Product Overview

Our high-temperature expansion valves (2-1/16" to 7-1/16") are engineered for critical thermal management in refinery, geothermal, and nuclear power systems. Featuring hard-alloy sprayed metal seals, these valves withstand extreme abrasion and corrosion while maintaining zero-leak performance under 650°F (Y-grade) and 5,000 PSI conditions.

Key Features & Benefits

1. Extreme Environment Durability

• Unmatched Temperature Range: 0°F to 650°F (Y-grade) for superheated steam/thermal oil applications.
• Pressure Resilience: 2,000–5,000 PSI with PSL1-PSL3G certification (API 6A compliant).
• Wear Resistance: Tungsten carbide/NiCr alloy-sprayed surfaces reduce erosion by 70% versus standard seals.

2. Precision Thermal Compensation

• Metal-to-Metal Seal Design: Ensures bubble-tight closure during rapid thermal cycling.
• Low-Friction Trim: Minimizes sticking risk after prolonged high-temperature exposure.

3. Compliance & Customization

• Material Grades: AA-EE alloys (including NACE MR0103 options for H₂S environments).
• Actuator Options: Manual lever, pneumatic spring-return, or hydraulic fail-safe configurations.
