Elastomer Seated Butterfly Valves – Type 58

The Chemline Type 58 Butterfly Valves are designed for ON/OFF and throttling control applications in heavy industries. They have a large size range, 1-1/2″ to 24″. All sizes have Polypropylene (PP) bodies as standard, offered at prices competitive with similar PVC body valves. A higher pressure/temperature safety factor is a bonus especially for hazardous services. Prices are much lower than similar PP body valves. A choice of disc and seat materials is available as well bodies in PVDF.
1 PVDF bodies and discs are available up to 12″;PP bodies and PVDF discs are available up to 16”
2 PVC or CPVC discs are available up to 10″
3 FKM (Viton®) or FKM-F are available up to 16″
NOTE: For PVDF bodies and discs up to 20”, PVC or CPVC discs up to 24”, FKM (Viton) seats up to 24” refer to Type 59
