The Beaver F41 Butterfly Valve has a concentric design, with the stem centred in the disc and a disc centred in the bore. The disc minimises resistance to the fluid which, coupled with the valve’s symmetric shape, provides high flow values with low pressure drop.
This valve allows bidirectional sealing with a resilient seat that is bonded to the body. This ensures complete shut-off with no leakage at the full pressure rating.
The high-strength one-piece through stem design resists corrosion and works at a rated pressure of 10 or 16 bar.
