INOXPA Divert Seat Valve K


The divert seat valve is a hygienic single seat pneumatically operated valve with a wide range of applications in the food-processing industry, beverage production, pharmaceutical and fine chemicals industries.

Operating principle

Seat valves are operated automatically by a single-acting or a double-acting pneumatic actuator. By supplying compressed air, the shaft is moved to place the valve in the “open” or “closed” position. The 180º rotation of the pneumatic cylinder of single-acting actuators allows to have a normally open or normally closed valve.

Design and features

  • Compact and robust design.
  • Normally closed valve (NC) in the standard version.
  • The valve can be changed to normally open (NO) by simply reversing the position of the pneumatic actuator.
  • Standard connections: weld (mm or inches).
  • Available sizes: from DN 25 / 1″ to DN 100 / 4″.
  • Easy assembly/disassembly of internal parts by loosening a clamp fastener.
  • Open lantern allows visual inspection of shaft sealing.
  • 360º adjustable body.
