When system integrity depends on proper flow direction, Hongxiang Brass Check Valves offer robust, maintenance-free backflow prevention for critical piping applications. Our industrial-grade valves combine precision engineering with durable materials to safeguard your equipment and processes.
Superior Construction Quality
Forged brass bodies with enhanced wall thickness for high-pressure service
316 stainless steel internal components resist corrosion and scaling
Dual-seal design with primary EPDM and secondary FKM sealing elements
Performance Advantages
Instant response with 0.03 second typical closure time
Bubble-tight shutoff prevents even minimal backflow
Silent operation eliminates water hammer concerns
Application Flexibility
Available in horizontal, vertical, and angled installation configurations
Multiple disc styles (swing, spring, ball) for specific flow characteristics
Customizable connection types and materials for special applications
| Series | Pressure Rating | Temperature Range | Flow Coefficient (Cv) | Certifications |
|---|---|---|---|---|
| HX-PRO | PN25 | -30°C to 150°C | 15-120 | API 594, ASME B16.34 |
| HX-ECO | PN16 | -20°C to 120°C | 8-75 | NSF 61, WRAS |
| HX-IND | PN40 | -40°C to 180°C | 25-200 | PED, CRN |
Material Specifications:
Body: CW617N brass (lead-free option available)
Trim: 316 stainless steel
Seats: Reinforced PTFE/EPDM composite
Springs: Inconel X-750 for high-cycle applications
Q: What's the proper orientation for installing these check valves?
A) Installation depends on series:
HX-PRO: Any orientation (universal design)
HX-ECO: Arrow must point upward ≥45° from horizontal
HX-IND: Horizontal pipe runs only (flanged models)
Q: How do I select the correct valve size for my application?
A) Consider these factors:
Maximum expected flow rate (select nearest higher Cv value)
System pressure differential
Media characteristics (viscosity, particulates)
Our engineers can provide detailed sizing calculations
Q: What's the expected service life under continuous operation?
A) Typical lifespan:
Water systems: 8-12 years
Chemical applications: 5-8 years (material dependent)
Steam service: 3-5 years (with regular inspection)
