Description
AUTOMA – Automatic Valve Tank Bottom Flush Valve
A “tank bottom flush valve” is a valve installed at the bottom of a tank, hopper or vessel, enabling the systematic draining or flushing of residual contents, sediments, slurries or fluids without leaving significant “dead zones”. The brand AUTOMA provides an automatic version that can be actuated (pneumatic or double acting) and built with industrial-grade materials. For example, the product page lists size range 25A to 250A, actuator model ATFV-Series, pneumatic double-action cylinder (with dry air), operating pressure 4-7 kg/cm², fluid temperature −40 °C to 120 °C, rating ANSI 150#.
Another AUTOMA brochure indicates “Tank Bottom Flush Valve” version with sizes 25A (2″) ~ 150A (6″), actuator model ATBB-Series, double acting, compressed dry air, ratings JIS 10K / ANSI 150# etc.
Thus the AUTOMA tank bottom flush valve is an industrial solution tailored for clean draining of tanks where remaining residues must be minimised and operation automated.
