VFA Aerre Inox Angle Seat Valve as Tank Bottom Valve

The Tank Bottom VFA 10º has a 10º vertical offset which enhances drainability while minimizing the internal sump within the vessel. The valve housing and the piping connections are self draining without dead-legs. The outlet connection is flush to the diaphragm to minimize hold-up volume, the standard outlet connection on the valve body is furnished on a 45° angle to the horizontal with an ASME-BPE ferrule, other optional end connections upon request include ISO/DIN connections. 45° angle outlet facilitate the ease of fit-up and permit using standard tubing to connect.

All moving parts in the actuator are completely isolated from contact with the process.
