  • suited to applications where pressure differential ΔP fluctuates or is very hard to define
  • they work properly regardless of the differential pressure ΔP on the valve – although they use process pressures for operation
  • they can be used from zero to the maximum PMAX operating pressure on which they have been designed
  • have relatively high flow resistance (low Kv) – design considerations
  • are sensitive to contamination – proper purity of the medium fluid should be ensured (filters application)
  • long actuation times – low connecting frequency
  • lifespan – less than for direct acting valves (several hundred of thousand work cycles)
