Female - male, butterfly handles

This category includes indoor-outdoor butterfly valves designed for use in heating, plumbing, and sanitary systems. These valves provide full flow capacity and are suitable for applications requiring reliable shut-off in both indoor and outdoor environments. They feature nickel-plated brass construction and internal/external FM threads for secure connections.

The valves operate within a temperature range of -20°C to +120°C and are certified for use with drinking water, making them ideal for residential and commercial installations where compliance with water safety standards is essential.

How to choose

Select the appropriate pressure rating (PN 25 to PN 50) based on the system’s operating conditions.
Match the valve size (1/4", 3/8", 1/2", 3/4", 1", or 5/4") to the pipe dimensions and flow requirements.
Ensure compatibility with existing fittings by checking for internal and external FM threading.
Confirm the material (nickel-plated brass CW617N) meets the corrosion resistance requirements of the installation environment.
