When the pressure is exceeded, the safety valve opens, allowing the
material to circulate within the safety valve plate.

The mechanical pressure control valve (2) can be manually adjusted up to
75 bar 7 500 kPa 1100 psi.
Plug
The plug (3) seals the material drain bore.

plate is moved.
For control purposes, the heating plate belongs to the reservoir.
