C30N Mosites Butterfly Valve
2" - 12"
150 PSI SERVICE
The Mosites C30N Butterfly Valve was developed to fill an industry need for a high cycle, fully elastomer lined butterfly valve. If your processes involve, chemicals, slurries, water, air or vapors, the C30N can solve your control problems. Incorporating the same unique features as the C30, the C30N meets API609 and MSS-SP 67 laying length (face-to-face) dimensions for quick replacement of standard butterfly valves.
Engineering Data for the C30N Valve
- A STEM - STEEL ASTM A-311 AISI GRADE C1144
One piece, full length stem with integral "DD" disc position indicator.
- B STEM RETAINER - ALLOY 625 ASTM B 446
Insures positive retention of stem.
- C BODY - CAST CARBON STEEL ASTM A-216 GRADE WCB WAFER OR LUG
Stronger than cast or ductile iron. Not subject to thermal shock. Also available in stainless steel and aluminum.
- D DISC INSERT - ATSM A-108 AND A-487 GRADE N
Lining material bonded to steel.
- E EXTERIOR FINISH
High Gloss Epoxy. Maximum protection from environmental corrosion.
- F GASKET SURFACE
Bonded to valve body. Will not "fold" on insertion between flanges.
- G BUSHING - RYTON/TFE
Reinforced top stabilizer bushing prevents side loading.
- H SECONDARY STEM SEAL
Pressure activated Viton seal ring.
- I & M PRIMARY STEM SEAL
Integrally molded O-Ring seal.
- J & L BEARING - TFE
Isolates elastomer sealing surfaces for long life and high cycle capability.
- K BODY LINER
Molded and bonded to body; prevents seat blowout.
- N BUSHING/RETAINER CUP - RYTON/TFE
Reinforced bottom stabilizer bushing prevents side loading and leak path to casting. Provides protection to stem from premature wear caused by metal-to-metal contact.
- O DISC TO STEM CONNECTION
Flat drive mechanism.
The quarter turn operation of the disc is easily accomplished by the handlever (with friction lock positioner) or weatherproof gear operator. For pneumatic or electric actuation packages, see Automated Valves. The Mosites Butterfly Valve meets ANSI B16.104, Class VI, bi directional shut-off specifications, and is for use with ANSI B 16.5 (2"-12") dimensional 150# flanges. The valve can be used for full vacuum and dead end service.
