Female - male, lever handles

This category includes internal-external lever ball valves designed for water shut-off in heating, plumbing and irrigation systems. These valves are commonly used in domestic and commercial installations where reliable flow control is required. They feature a lever mechanism for easy operation and are suitable for temperatures ranging from -20°C to +120°C.

The PERFECTA range includes models with PN ratings from 16 to 50, available in sizes from 1/2" up to 6/4" with FM (female metric) internal and external threading. The lever design provides a clear open/close indication and ensures smooth actuation even under pressure.

How to choose

• Select the correct size (e.g., 1/2", 3/4", 1", up to 6/4") based on the pipe diameter and flow requirements.
• Ensure compatibility with FM internal and external threading for secure and leak-free connections.
• Confirm PN rating matches the system pressure (e.g., PN 16 for low-pressure systems, PN 50 for high-pressure applications).
• Verify temperature suitability for the operating environment, particularly if exposed to freezing conditions or hot water.
