Why Tank Bottom Valves

Normally, an ordinary Open/Closed valve or ball valve is used for draining a tank. For many cases, this is indeed sufficient. However, in some situation, the use of tank

bottom valves is essential. Particular examples for such need include the situation of installation, media, possible dead space or crusting formation.

Criteria for the Use of Tank Bottom Valves

Various aspects have to be considered for the use of tank bottom valves. The main criteria can be described by the following characteristics:

Medium:

The relevant medium is not always a clear liquid. Solids or even clots make the use of “normal” valves impossible. Due to their design, RITAG tank bottom valves ensure free passage and thus the possibility of clean draining, even for liquids with significant solids.

Crusting: 

Tank draining is prevented if the outlet is blocked by a crust. RITAG tank bottom valves are able to break through such crusts so that draining is easily possible.

Dead space:

A dead space may occur in the socket of a tank outlet. This impedes the full mixing of the

medium. In such cases, RITAG tank bottom valves could contribute to avoid dead spaces.
