Membrane Pressure Relief Valves VHS-C

As its predecessor, the VHS-type, the VHS-C Pressure Relief Valve is the last safety net when abnormal pressure conditions endanger the silo structure. This is why sudden excess or suction pressure inside the silo has to be dealt with instantly. Even though ideally a VHS-C Pressure Relief Valve should never have to go into action, it must be efficient and reliable if needed.

Technical Features


VHS-C Pressure Relief Valves – the evolution of the VHS-type – consist of a cylindrically shaped polymer body with flanged connection spigot to the silo, an exhaust outlet elbow for duct connection, an elastic membrane able to re-establish pressure balance instantaneously, a counterweight kit to keep the valve closed under normal conditions, and a weather protection cover.

  • Vertical carbon steel or 304 stainless steel spigot
  • Casing diameter: 273 mm (10 in)
  • Exhaust outlet spout for connection to centralised suction system
  • Mechanical set-up for inductive signalling sensor
  • Limited number of components
  • Counterweight system never in contact with dust
  • Membrane and conveying pipe of special geometry manufactured from innovative materials
  • SINT engineering polymer casing and weather protection cover
  • Special properties of membrane and elbow prevent clogging and formation of material crusts
  • EN 1935/2004-compliance
  • Manhole
  • Inductive sensors
  • Bird net
  • Setting kit
