Selection criteria for double eccentric dampers

When selecting double eccentric dampers, several key parameters should be taken into account:

• Nominal diameter (DN)
• Nominal pressure (PN)
• Body and disc material
• Type of seal
• Drive type (manual, pneumatic, electric)

At Onninen we offer double eccentric butterfly valves in diameters from DN50 to DN1200.   Models are available with nominal pressures up to PN100. We select them to suit specific installation requirements. Construction materials include cast iron, carbon steel and stainless steel.

We recently completed a project for a large chemical plant. It required double-eccentric butterfly valves with high chemical resistance. We used duplex steel models with PTFE seals. They provided trouble-free operation in an aggressive environment.

Many customers ask us about the possibilities of damper automation.   Our offer includes comprehensive drive solutions.   These include pneumatic, hydraulic and electric actuators. We select them individually to suit the application requirements.
