Seal-Less Butterfly Valves
Usual butterfly valves have a water-tight sealing method between disc and body seat that is maintained by a rubber ring. This increases cost because the rubber is damaged by high frequency valve operation, exposure to chemical flow and high temperature. The disc pressed type butterfly valves provide:

- Low maintenance expense
- Long durability
- Drop-tight sealing
- Easy function

Quality design features are standard including metal-to-metal seating which provides high strength and wear resistant stainless steel components.
