Receiving And Installation; Checking The Shipment; Delivery And Unpacking; Identification - INOXPA OVERFLOW Installation, Service And Maintenance Instructions

_____________________________________________________________________________________

3.1. CHECKING THE SHIPMENT

The received valve must be checked to ensure that it is adapted to the working
conditions in the classified area and the conditions stated in the order

3.2. DELIVERY AND UNPACKING

3.2.1. Delivery
3.2.2. Unpacking

3.3. IDENTIFICATION

In the case of ATEX valves, additional identification will be established with the following:
The temperature class and the maximum surface temperature depend on the temperature of the product to
be stirred and the ambient temperature.
Temperature

T6
T5
T4
T3
Maximum surface temperature for explosive dust atmospheres
Maximum

T85 °C
T100 ºC
T125 ºC
T 200 °C

3.4. LOCATION

3.5. FLOW DIRECTION

3.6. OVERFLOW VALVE POSITION

3.7. ASSEMBLY

To reduce the risk of static electricity, the assembly must be earthed to ensure
electrical continuity between the pipes and the valve
