Perguntas frequentes

1º trimestre: What is the difference between wafer-style and lug-style butterfly valves?

UM: Wafer-style butterfly valves are clamped between two flanges using through-bolts and cannot isolate flow from a single side. Lug-style butterfly valves feature threaded lugs on both sides, allowing each flange to be bolted independently; this supports end-of-line service (dead-end isolation), enabling the removal of downstream piping for maintenance without draining the entire system. Lug-style valves are better suited for applications requiring regular maintenance.

2º trimestre: What are the differences between EPDM, NBR, and plastic seats?

UM: EPDM (Monômero de etileno propileno dieno) is resistant to water and steam, with a maximum temperature of +130°C, and is cost-effective; NBR (Nitrile Butadiene Rubber) is resistant to oil and fuel, with a maximum temperature of +100°C; plastic seats withstand high temperatures up to +220°C and are suitable for steam and high-temperature media. The choice depends on your specific medium and temperature requirements.

3º trimestre: Can this butterfly valve be used for steam?

UM: Sim. Para aplicações de vapor, the plastic seat option is recommended, as it supports temperatures up to +220°C. EPDM seats are also suitable for saturated steam (up to +130°C). Please specify the steam operating conditions when placing your order to ensure the correct seat configuration.

4º trimestre: Can lug-style butterfly valves be fitted with electric or pneumatic actuators?

UM: Sim. The valve’s top flange complies with the ISO 5211 padrão, allowing for the direct mounting of electric or pneumatic actuators without the need for additional intermediate adapters. This simplifies automation upgrades and on-site installation.

Q5: What are the advantages of FBE epoxy coating?

UM: Fusion-Bonded Epoxy (FBE) coating, applied via electrostatic spraying and heat curing, offers excellent adhesion, resistência à corrosão, and wear resistance. Coating both internal and external surfaces ensures reliable long-term operation in humid, corrosive, or harsh environments, extending the service life and reducing maintenance frequency.
