1. Size: 2"to26"wafer type, lug type
2. Designs: DIN and ANSI.
3. Materials: Body: Carbon steel, 304S. S and 316S. S Disc: 304S. S and 316S. S Shaft: 416S. S and 316S. S, 17-4pH. Seat: EPDM/RPTEM Bushing: Glass backed PTFE
4. Working Pressure: 2"to6" 40bar 8"to26" 25bar
5. Specification:
1) The double offset design of the double eccentric butterfly valve assures reduced seat wear and bidirectional seal, zero leakage. When open the valve, the disc does not contact the seat, so the seat life is extended and operating torques are reduced, then it is more easier for user's operating.
2) General: Standard valves tested to MSS SP-61. API 598 testing available on request.
For 2" through 24" sizes: Face-to-face dimensions meet, within specified tolerance, MSS SP-68 and API 609 requirements
