Installation
Hydraulic loading & unloading system HV 215
We highly recommend that only qualified staff should carry out installation work in accordance with these
installation instructions. The manufacturer expressly rejects any claims for damage caused by improper installation.
All parts to be fitted must meet the technical requirements specified by the manufacturer. All genuine parts are
guaranteed to comply with these requirements.
For installation work choose lifting devices that are specified for the respective weights. Use only suitable and
proper lifting devices.
When welding observe legal regulations and in-house guidelines concerning welded connections. Before welding
clean all spots to be welded.
Make sure that the gaskets of the flanged connections are exactly placed between the flanges. Clean all seating
surfaces before installing the equipment.
Before installing the valves remove the transport packing and all transit protection plugs for end connections.
Install the equipment in the following order:
n
Mounting flanges
n Bottom valve HWV 205/ - DN 80
n Bottom valve HWV 25/ - DN 80
n Cable routing
n Operating devices BV 0
n Connecting lines
n Attaching operating plates HV 25
n Attaching plates indicating fluids
Mounting flange
The mounting flanges for bottom valves type HWV 205/ - DN 80 and HWV 25/ - DN 80 have the same
form and can be installed in the same way.
They are not scope of supply of the loading & unloading system HV 25 but can be ordered from Gestra.
Valve mounting flanges made from the following materials are available:
n
P355NL (.0566, old: TStE 355)
n S420NL (.892, old: TStE 420)
n P460NL (.895, old: TStE 460)
Further materials are available on request.
Gestra supplies valve mounting flanges with a standard diameter of 430
+6 mm. To avoid a wall thickness
misalignment between the valve mounting flange and the tank wall, adjust the outside diameter D to the
thickness S of the tank car (see drawing on page 6). Make sure that the weld joint produced is in compliance
with the specifications of the tank manufacturer.
The valve mounting flanges are welded into the bottom of the vessel according to the specifications of the
local welding authority.
To calculate the dimensions of the pressure vessel to AD-B/ B9, refer to the drawing ( see page 6) in which
the dimensions of the reinforcement are indicated.
