AEGIS Flow Technologies, L.L.C.

- Model BFV Series - Butterfly Valves



The Aegis BFV series fully lined high performance butterfly valves feature the most advanced technology available for controlling and isolating corrosive, ultra-pure, and highly-toxic process liquids and gases. The BVF series valves are designed, engineered, and manufactured under a company-committed quality assurance process that has been audited and approved by the SQS ISO 9001:2000 for Quality and Management Systems and the PED (Pressure Equipment Directive) 97/23/EG for mechanical integrity. The unique geometric profiles of the disc and liner eliminate the cold flow and deformation issues typical of conventional lined butterfly valves, resulting in a conditional, environmentally safe, life time shaft seal guarantee.
