PTFE lined butterfly valves

admin-fortek — Thu, 27 Jan 2022 21:21:11 +0000

The PTFE lined butterfly valves are designed to control corrosive fluids in applications requiring high reliability, perfect seal, constant torque and poor maintenance.

The PTFE lined butterfly valves are suitable for different uses and industries (chemical, pharmaceutical, cosmetics, semiconductors – UPW, foundries, mining).

The PTFE lined butterfly valves ensure a tight “bubble proof” seal in both directions, in accordance with EN 12266-1.

The PTFE lined butterfly valves are provided with two series of cup springs which ensure the exact pressure to keep in contact the two sealing surfaces.

In addition, the PTFE lined butterfly valves ensure high sealing of the flanges also thanks to the covering. They are equipped with thin disk/shaft in one piece coated with a layer of molded PFA with a thickness of 3 mm.
