Giant Elastomer Seated Butterfly Valves – GY Series

The Chemline GY Series Giant Butterfly valve has a full elastomeric seat with tight sealing. Polypropylene (PP) is a durable material offering high impact strength. This valve’s weight is a fraction of the weight of cast iron. GY Series valves are designed for long service lift in corrosive environments. They are ideal for fibreglass ducting handling corrosive gases or HPDE (high density polyethylene) pipe transporting corrosive liquids or water. Applications include acid plants, hydrometallurical plants, landfills and aquariums.
