Rectangular throttle valve Type RENA | ACI Industriearmaturen GmbH

Rectangular damper type RENA

We designed RENA as a single- or multi-vane system. Unless you specify otherwise, they are produced in accordance with the DIN 24193 standard. RENA’s multi-vane system provides better control characteristics and it can be ordered in either a synchronous or asynchronous version. Upon request we can also outfit RENA with a refractory lining made of concrete or mineral wool. The „sealing air“ model is 100% leak-free and therefore completely air tight. As with all our valves, RENA is very robust, low in maintenance and safe. Even under extreme conditions, RENA offers a long service life, very low probability of failure and great reliability.

Other advantages RENA offers:

  • Sealing Class I, II, III per FCI 70-2 1976 (R1982) or better.
  • The sealing air model is 100% air tight.
  • Class I optimized for dust-laden media
  • Flange valve with flanges as per DIN 24193 or in specified dimensions.
  • DN 50×50 to 2000×2000 DN (other sizes available separately).
  • For air, flue gas, waste gas.
  • Operating temperatures up to 1050°C
  • Low torque due to „low-friction packing.“
  • Integrated ISO 5211 interfaces.
  • Conversion kit available for easy, subsequent RENA automation.
  • Corrosion protection included in the standard model.
  • Actuation by hand lever, worm drive, electric, pneumatic, hydraulic
  • Fire-resistant lining available (refractory concrete, fireproof mineral wool).
  • 100% air tight
