butterfly valves

Concentric butterfly valve with an electrical actuator

Concentric butterfly valves has a resilient rubber seal with a metallic disc, that is placed concentrically between the shaft center line and the disc center line.

This valve type are designed to have an optimal mix of structural stability, flow efficiency and effective sealing properties, taking advantage of its light weight manufacture, compact design, low maintenance and ease of operation.

Butterfly valves can be operated via quarter-turn hand levers, or via gear, electrical or pneumatic actuators.


Concentric Babcock Valves are produced in sizes from 24″ to 200″, with an ANSI classification from 150 to 600 lb.


We produce butterfly valves in a wide range of materials, including high alloys (exotic), like duplex stainless steels, hastelloy, inconel, monel, titanium, etc. Modern techniques and customer requirements continuously impose changes in materials and design, due to which any reference not included in this web will also be supplied.
