Double eccentric butterfly valves

The butterfly valves are based on a double eccentric operating principle, in which the disk does not touch the seal in the open position. This double eccentricity guarantees a longer lifetime of the system while at the same time reducing maintenance costs.

Standard valves contact the valve seal when open, causing it to degrade quickly. GF Piping Systems' butterfly valves do not, thanks to the double eccentric design, which maximizes service life.

A streamlined design significantly reduces torque, making it simple to switch the butterfly valve from ‘open’ to ‘closed’, thereby improving operational efficiency.
