Horizontal check valves

Horizontal check valves in this category are designed for use in heating, plumbing, and irrigation systems. They prevent backflow in pipelines and are suitable for installation in pump circuits, suction baskets, and filtration systems. The valves are available in a range of sizes from 1/2" to 4" FF (female-female) threaded connections and offer either metal-to-metal or soft-seal disc configurations. These valves operate at a nominal pressure of PN 10 and a maximum temperature of +80°C. The materials used include brass CW617N, and some models are certified for potable water applications.

How to choose

• Choose the correct size (e.g., 1/2", 3/4", 1", up to 4") to match the pipe diameter and flow requirements.
• Select the appropriate sealing type—metal-to-metal for durability or soft disc seal for quieter operation and tighter shut-off.
• Ensure compatibility with the connection type (FF thread) and system pressure (PN 10).
• Verify if the valve is suitable for potable water if required for drinking water systems.
