New large diameter butterfly valves

GF Piping Systems has expanded its Type 567 butterfly valve line in larger diameter sizes.  The distinctive double eccentric off-center designed wafer style butterfly valves are now available in 14” to 24” sizes.  The systems modular design principle allows users to quickly and easily exchange individual system components at very little expense. The valves are ideal for water treatment, power plants, chemical process industry and cooling equipment.  With a 50% lower actuation torque compared to a centric butterfly due to the double eccentric operating principle, abrasion can be reduced noticeably.  The integrated electric position indicator is in the mounting flange and all components which are in contact with the media are made of piping materials, minimizing permeation.  They can be pneumatically or electrically actuated and a fine adjustment lever allows the disc to be opened at any angle from 0° to 90°.
