**Key Features:**
This internal thread ball check valve is designed for reliable performance in a wide range of industrial applications. It features a unidirectional flow, ensuring that the fluid moves only in one direction, preventing backflow. The valve is constructed with high-quality materials such as cast iron GG25 or ductile iron GGG40, providing durability and resistance to corrosion.
The valve is available in various sizes, from DN25 to DN80, making it suitable for both small and large piping systems. It is compatible with both BSP and BSPT threaded ends, offering flexibility in installation. The operating temperature range is from -10°C to +80°C, making it ideal for a variety of environments.
**Surface Protection:**
The body is coated with FBE (Fusion Bonded Epoxy) powder, in a sky blue color (RAL 5005), with a minimum thickness of 200μm, providing excellent protection against corrosion and wear.
