  • They provide in-line vacuum relief in the Vacuum Systems and provide safe operation conditions for Blowers and Vacuum Vessel / Hopper
  • For air only applications
  • In a pressure system with the BPV, the air is vented out to the atmosphere when not needed while changing Diverter Valve direction instead of switching off the Blower
  • They are available in different sizes from 50 to 200mm sizes and can be installed in any position
  • Body construction is Cast Aluminum with Plunger made of rubberized disc. This Valve is Pneumatically Operated with Reed Switches as Position Sensor

SV-A (Scale Valve - A)

  • Scale Valve is used to divert the bulk solids in pneumatic transit to receiving vessels. This diversion can be used for such things as In-Line Filling or Bulk Storage Bins, Scale Hoppers / Weigh Hoppers or Process Hoppers
  • In the straight through position the inlet and exit points are aligned through the machined bore of a rotating paddle so that the material passes straight through
  • Being set in diverter position, the air and the material enter the inlet port to be directed downwards by the diversion paddle, into receiving vessel. Air alone gets vented through outlet
  • Final Filtration or Residual Conveying Air can be carried out at a location remote from the receiving vessel
  • It is available in Cast Iron, Aluminium and Stainless-Steel. A simple construction with minimal contact area and minimal process loss
  • Scale Valve – A offered in sizes from 50, 80, 100 & 500mm. Complete air controls are provided as standard, including the Pneumatic Cylinder and Solenoid with Control Unit
  • Available with Flange or Pipe connections
