SI/DP In-Tank Valve

Brand: PROTEGO
Protego SI/DP in-tank valves are used as additional shut-off valves for full containment tank systems, e.g. for storing liquefied gases, cryogenic gases, other low temperature products or chemicals.

Generally a gate valve that is supplied by the user and serves for normal operation is connected to the external nozzle of the housing.

The in-tank valve is kept open under normal operating conditions. It is only closed for longer shut-downs, in case of emergency or for necessary repairs to the gate valve.

The key feature of these valve devices is the actual shut-off element that is located inside the tank.

The advantage of this valve design is that it prevents any leakage from the tank in the event of any external parts of the assembly getting damaged.

It also means that maintenance work can be carried out on the actuator without any need to dismantle the pipeline or empty the tank.

We recommend to use bottom drain valve Protego NB/AP for emptying the tank completely.
