We know that the actuation forces in poppet valves are relatively large, they are much smaller in piston spool valves, because the valves do not have to be switched against any forces generated by the operating pressure. The problem with overlap is also easily solved. Piston spool valve However, there are drawbacks with this valve type too. For example, the strokes for switching operating positions are longer than with poppet valves. These longer strokes and the requirement for several pistons mean that the piston spool valves typically must be longer. In terms of manufacturing, the piston spool valves are also more challenging, particularly when it comes to sealing technology.

The cartridge principle for spool valves
  • One solution to the problem described in Figure 6 is to use moulded seals in metal cages. The seals are thus retained in recesses in the metal housing; the so-called cartridge principle. The advantage with this solution is that the seal will not be pulled out of position even at an operating pressure of up to 16 bar, thanks to the special design of the metal cage holding the seal. This ensures a significantly longer service life. In addition, the improved sealing between the piston and the elastomer seal enables cartridge principle valves to be reliably used for vacuum applications.

Features:
  • The high pressure and the restriction of the channel produce a higher air flow rate through the valve.
  • The pressure in the valve is reduced due to the increasing air flow rate.
  • The greater static pressure on the groove base creates an imbalance of forces on the seal forcing the seal to protrude more out of the groove.
  • When the spool switches positions, the seal friction forces are now higher resulting in premature wear
