T-smart Tank Bottom Valve 4000

T-smart Tank Bottom Valves 4000 are used to shut off fluid media at vessels or tanks. They are designed to be fitted at the lowest point of the tank bottom to shut-off the media flush with the tank bottom without any kind of sump.

The pocket-free design provides complete draining of the tank and optimal CIP/SIP cleaning. The extremely compact design allows T-smart tank bottom valves to be fitted into the tightest of spaces.


Thanks to the robust design of the body connection flange, the valve can be welded into place without any distortion. T-smart tank bottom valves are fitted with single-acting pneumatic actuators type NC (normally closed), alternatively type NO (normally open), and are available in 2 different housing combinations.
