The AV-131 Cast Iron Dual Plate Check Valve, Class-125 is designed to prevent backflow in various systems, including water, oil, and air applications. Its dual plate design features two spring-loaded plates that close automatically, reducing water hammer and ensuring quick shutoff.
Key Features:
Material: The valve body is made from cast iron, offering durability and corrosion resistance. The plates are typically stainless steel for enhanced longevity.
Class-125 Rating: This indicates suitability for systems with a maximum pressure of 125 psi at standard operating temperatures (around 200°F for cast iron).
Compact Design: The wafer-type construction makes it lightweight and space-saving, fitting easily between flanges.
End Connections: Available with wafer or flanged connections for straightforward installation.
Application Versatility:
Water: The cast iron body with protective coatings and stainless steel internals make it ideal for potable water, wastewater, and irrigation systems. It effectively prevents backflow, safeguarding system components.
Oil: Suitable for low to moderate pressure oil systems, it handles various oils, including hydraulic and lubricating oils, within its pressure and temperature limits.
Air: The valve provides minimal leakage and low pressure drop, essential for efficient air flow in compressed air systems. It ensures reliable closure, preventing backflow in industrial applications.
Benefits:
- Cost-effective: Cast iron is a budget-friendly material choice.
- Reduced Water Hammer: The spring-assisted closure minimizes pressure surges.
- Low Maintenance: Its simple design with minimal moving parts reduces maintenance needs.
This valve’s versatility across water, oil, and air applications, combined with its robust design and cost-efficiency, makes it a reliable choice for many industrial and commercial systems. Proper sizing and material compatibility ensure optimal performance and longevity in various operating conditions.
