Rubber lined butterfly valves

Rubber lined ARI butterfly valves are perfectly suitable for shut-off valves on both large and small diameter low-pressure water pipes, for example. They are lightweight, installation-friendly, easy to use and tight.

Installation options include a model to be installed between flanges and a flanged model or a model fitted with threaded lugs, a so-called end flange model.

Materials according to the process medium

Typical process media are process cooling liquids, clean and fresh water. You can select a suitable material combination for each medium application.

Valves can be equipped with pneumatic or electric actuators. They can also be installed underground and operated via an extension stem from above the ground.

Large butterfly valves should be installed in the piping so that the valve stem is horizontal.
