Product Description
Stop Backflow. Save Energy. Protect Equipment. Check Valve
Engineered for critical performance in demanding applications, our Series Name Check Valves provide absolute, automatic protection against reverse flow. Utilizing advanced design and durable materials, they deliver zero-leak sealing to safeguard system integrity, optimize energy efficiency, and prevent costly damage to pumps, compressors, and downstream equipment.
These valves are built to operate reliably under specified pressure ranges with a swift, positive closure mechanism that minimizes pressure drop and water hammer. The robust construction ensures longevity with minimal maintenance, even in challenging environments involving high cycle rates, varying temperatures, or corrosive media.
Core Features & Technical Advantages
- Unidirectional Flow Assurance: Automatic, fail-safe operation prevents hazardous or inefficient media backflow, ensuring system safety and process continuity.
- Zero-Leak Sealing: Precision-mated sealing surfaces (e.g., metal-to-metal, reinforced elastomer) guarantee tight closure, eliminating internal leakage and maximizing volumetric efficiency.
- Energy & Operational Efficiency: Low opening pressure and streamlined internal geometry reduce system resistance, lowering pumping costs and supporting sustainable operations.
- Equipment Protection: By preventing reverse rotation and pressure surges, our valves extend the service life of critical assets like pumps, meters, and filtration systems.
- Robust Construction & Versatility: Available in a range of materials (e.g., stainless steel, ductile iron, specialized alloys) and configurations (swing, lift, dual-plate, silent), tailored for water/wastewater, HVAC, oil & gas, chemical processing, and power generation applications.
- Low Maintenance Design: Simple, reliable operation with self-cleaning capabilities where applicable, reducing total cost of ownership and downtime.
Applications
Ideal for installation in pump discharge lines, cooling circuits, mixing systems, and as isolation valves to protect components from backflow contamination, siphoning, or pressure loss.
Key Specifications
| Size Range | ½" to 48" (DN15 to DN1200) |
| Pressure Class | ANSI 125 to 2500 (PN10 to PN420) |
| Temperature Range | -20°F to 1000°F (-29°C to 538°C), dependent on model and trim |
| End Connections | Flanged, Wafer, Threaded, Butt-Weld |
| Compliance | Meets or exceeds API 594, API 6D, AWWA C508, and other relevant international standards |
More than just a component, the Series Name Check Valve is a vital investment in your system's reliability and efficiency. It eliminates the risks of backflow-related failures, reduces energy waste, and provides durable protection that translates into lower operational costs and enhanced safety.
