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

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.
