Introducing the Type 578 Lug Style Butterfly Valve

Jan 2, 2015 10:00 AM

We are expanding the Georg Fischer butterfly valve product line to include the new Type 578 plastic-bodied lug-style valve. This valve incorporates many of the industry-tested design features that our butterfly valves are known for:

1. The double eccentric disk design disengages the disk from the seal while the valve is opening and closing, resulting in reduced component wear and decreased required operating torque.

  • Reduces required operating torque by approximately 50%

2. The glass-filled polypropylene outer housing provides UV and chemical resistance while increasing impact strength.

3. The truly non-wetted 316 stainless steel shaft is protected by a precision bushing assembly featuring a redundant o-ring design.



  • Size: 2”–12”
  • Body: Glass filled PP with overmolded SS316 lugs
  • ANSI 150 bolt pattern
  • Materials: PVC, CPVC, PP, ABS and PVDF
  • Stem: 316 stainless steel
  • Seal: EPDM or FPM; PTFE seals available upon request
  • Operation: Bare shaft, lever, gear
  • Actuation: Electric and pneumatic
