type DB 13 - BD 40
The DB pressure relief valves are direct-controled piston
valves. If the preset pressure is exceeded, it opens and
feeds the medium back into the tank via a bypass pipe
(leakage pipe).
Installation
Pressure relief valves series DB must be installed in an
upright position. The valve will be installed in the discharge
pipe with a bypass line. The bypass pipe at the outlet of the
valve is returned pressureless to the tank.
Fluids: Oils up to a viscosity of 350 mm²/sec (special design on request)
