New PTFE-lined valve from Nil-Cor Composite Valves

The new PTFE-lined advanced composite butterfly valve from Nil-Cor provides maximum corrosion resistance inside and out, with a light-weight body successfully tested to 800 PSI

The new PTFE-lined advanced composite butterfly valve from Nil-Cor provides maximum corrosion resistance inside and out.

The butterfly-valve's light-weight body is made of corrosion-resistant fiberglass-reinforced cast epoxy.

The body, successfully tested to 800 PSI, combines outstanding strength and durability with high-heat resistance in corrosive environments.

The valve features an integral ISO 5211 actuator mounting flange for strength and convenience.

Internally, the Nil-Cor valve has a PTFE lining and a PFA-encapsulated, stainless steel, single-piece disc and shaft for superior strength and corrosion resistance.

Bolts that secure the two-piece body are made of high-strength steel, coated with Teflon and isolated inside the body with a leak proof cap.

The Nil-Cor butterfly valve can be installed between lined pipe fittings, metallic raised-face pipe fittings, unlined FRP fittings and is excellent in dual-laminate piping systems.

The valve is ideal for handling chemicals such as chlorinated acid brine, very hot, concentrated inorganic acids, caustics, petrochemicals and phenols which are corrosive to vinyl ester and other valve materials.

Additional applications include ultra-pure and clean services.

Nil-Cor, a subsidiary of Dresser, is the originator of advanced composite technology used for the design and manufacture of ball, butterfly and check valves.

Certified to ISO 9001 and the European PED, Nil-Cor has been supplying composite-valve solutions to the chemical process industry for over 27 years.
