Industrial Butterfly Valve Solutions
XHVAL specializes in high-performance butterfly valves for critical applications. Our triple eccentric valves deliver metal-to-metal sealing for extreme temperatures, while double eccentric valves provide cost-effective reliability for general industrial use. ✓ API 607 Fire-Safe | ✓ Class VI Zero Leakage | ✓ 28+ Years Experience
01.Triple Offset Design Technology
The innovative triple offset geometry eliminates rubbing between disc and seat during operation. This cam-action design ensures frictionless opening/closing and extends service life by 20%+ compared to conventional valves. Three Geometric Offsets: • 1st Offset: Shaft behind sealing plane - creates cam action • 2nd Offset: Shaft to side of centerline - eliminates interference • 3rd Offset: Conical sealing angle - torque-seated contact Technical Advantages: ✓ Zero leakage (Class VI per API 598) ✓ Metal-to-metal seating ✓ Temperature: -196°C to +650°C ✓ API 607 fire-safe certified
02.Fire-Safe Certified Performance
Every triple eccentric valve undergoes rigorous fire-safe testing per API 607 and ISO 10497 standards. The metal seat maintains tight shutoff even after soft seal materials are destroyed. Critical Applications: 🛢️ Oil & Gas - Refinery, pipeline, LNG terminals ⚡ Power Generation - Steam isolation, turbine bypass 🏭 Petrochemical - Catalytic cracking, ethylene ❄️ Cryogenic - LNG liquefaction (-196°C) 🔥 High Temperature - Steam, hot oil (+650°C) Size: DN50-DN3000 | Pressure: PN10-PN160 / Class 150-2500
High-performance butterfly valve Switching Times test platform
Our state-of-the-art testing laboratory ensures every butterfly valve meets international standards. We perform comprehensive validation including: Testing Capabilities: • Hydrostatic shell test (1.5x rated pressure) • Seat leakage test per API 598 (Class VI) • Fire-safe test per API 607 / ISO 10497 • Operational torque verification • Cycle testing: 10,000+ operations
03.Double Eccentric High Performance
Our double eccentric butterfly valves offer an optimal balance of performance and cost. The dual offset design reduces seat wear while providing reliable Class IV-V shutoff for general industrial applications. Design Features: • Resilient PTFE, RTFE, or EPDM seats • Bi-directional tight shutoff • Lower torque = smaller actuators • Temperature: -40°C to +200°C • Size: DN50-DN2000 | Pressure: PN10-PN25 Cost Advantages: ✓ 30-40% lower cost than triple eccentric ✓ Easy in-line maintenance ✓ Replaceable soft seats
04.Versatile Industrial Applications
Double eccentric valves are the go-to solution for water, HVAC, chemical, and general industrial applications where cost-effectiveness is a priority. Primary Industries: 💧 Water Treatment - Municipal supply, wastewater, desalination 🌡️ HVAC - Chilled water, hot water, district heating 🧪 Chemical - Processing, storage, pharmaceutical ⚓ Marine - Ballast water, cooling systems Why Choose Double Eccentric? • Perfect for clean liquids and gases • Economical choice for non-critical applications • NSF/ANSI 61 certified for potable water • Proven reliability in 10,000+ installations
