** – valve width without coil
- 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)
