Butterfly Valves Overview

GF Piping Systems Our System Solution Overview Butterfly Valves

Benefi ts Butterfly Valves From GF – Right Choice The wide range of innovative valves and continual developments in modularity and multifunctionality accentuate GF Piping Systems’ role as a leading system supplier. The versatile butterfl y valves feature not only great fl exibility in how they can be used but also a high level of quality and durability. Aligned with the individual requirements of our customers, the valves are reliable, effi cient and economical in use, thus providing you with sustainable added value. Longer life means higher profi tability The butterfl y valves are based on a double eccentric operat- ing 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 main- tenance costs. Easy and quick The new generation of butterfl y valves has several convinc- ing features, compared to earlier valve designs, such as an actuation torque that is up to 50 % lower when changing from the open to closed position. The advantage of minimal force and maximum effi ciency not only makes the valve easier to operate, but also allows using smaller and more economical actuators. Optimal corrosion resistance Due to the high performance plastics implemented in these valves, excellent resistance to corrosion is guaranteed. Max- imum corrosion resistance reduces maintenance and repair costs and more importantly ensures longterm and safe use in transporting aggressive media in demanding industries such as the chemicals industry. Universal application options The application oriented selection of diverse materials for housing and seals, the choice of manual, pneumatic and electric actuators as well as all the possible dimensions ranging from DN50 to DN600 render the universal character of the valve system. Combined with the modularity of the in- dividual components, the system off ers maximum versatility and freedom of choice. 2
