BUTTERFLY VALVES

Butterfly valves are used to regulate or shut-off a flow, and are the preferred solution in larges sizes up to 4000 mm.

FAMAT SA can supply different types, depending on the application.

Butterfly valves with centric disc

They are the most economical type, best adapted for pressure up to 16 bars, and in sizes up to 2000 mm.

There are three different models:

• Wafer type, PN6 to PN16, or ANSI 150, sizes 1” to 20”
  1. Body materials: ductile iron, carbon steel, stainless steel, Ni-Al-Br with rubber-lining
  2. Disc: in stainless steel 316L, Ni-Al-Br.
• Lug type, PN6 to PN16, or ANSI 150, sizes 2” to 26”
  1. Body materials: ductile iron, carbon steel, stainless steel, Ni-Al-Br with rubber-lining
  2. Disc: in stainless steel 316L, Ni-Al-Br.
• Double flanged, PN6 to PN16, or ANSI 150, sizes 2” to 80”
  1. Body materials: ductile iron, carbon steel, stainless steel, Ni-Al-Br with rubber-lining
  2. Disc: in stainless steel 316L, Ni-Al-Br.

Butterfly valves with double eccentric disc, sizes 4” to 120”

Are recommended for pressures above 16 bars, in particular for large sizes up to 4000 mm. These valves are mostly double-flanged, for pressures up to 40 bars.

1. Body materials: ductile iron, carbon steel, stainless steel, can be rubber-lined.
2. Disc: in ductile iron, stainless steel 316L, Ni-Al-Br.

Butterfly valves with triple eccentric disc 

This construction allows a tightness metal-to-metal and can present many advantages or alternative to Gate valves as applicable also for high temperature and pressure.

1. Body and Disc materials: are in A216WCB, WC6, WC9, CI2A, CF8M, in sizes 4” to 80” and pressure classes ANSI 150, 300, 600, 900.

All accessories and equipment are available:

• Handgears, electric-hydraulic or pneumatic actuators
• Fire-Safe for metal – seat
• Extensions for cryogenic
