Non-Return Valve RSV

Schmalz has developed the Non-Return Valve RSV, with a nominal diameter from 6 mm to 54 mm, for maintaining the vacuum pressure in the case of a power failure or a failure of the vacuum generator and can also be used with energy-saving systems when handling nonporous materials.

This pressure-reducing valve is equipped with a spring-loaded seat valve, aluminium brass body, seat made of synthetic rubber, and gasket made of nylon and can be installed in any orientation.

  • Closure of the vacuum line in order to maintain the system vacuum in the case, for example, of a power failure
  • Wide range of nominal diameters
  • Very low to very high nominal flow rates possible
  • Very small size
  • Also suitable for use in restricted spaces
