Piloted relief valve

Piloted relief valve

Our piloted relief valve :

Lower production losses with operating pressures close to the set pressure

Better opening/closing and tightness performances than those of spring relief valves

DN 25 to DN 150

1" à 6"

PN 10 to PN100

150 to 600 lbs

Type: 501

Functions – Piloted relief valve

♦ Safety device ; in-line or on vessel

Features

♦ Immediate or modulating action
♦ Operating very close to the set pressure : no production/yield loss
♦ Not sensitive to counter pressure : easier line construction, bellows not required
♦ Shorter overall dimension than spring loaded safety valves
♦ Very good tightness : the more the fluid pressure increases, the more the disc presses the nozzle ; tightness up to set pressure
♦ Easy maintenance
♦ Short or long nozzle
♦ Compliance with PED 97/23/EC.

Operation

no operator
