Throttle valves: JACOB throttle valves and regulators precisely control the air flow and product transport and can be flexibly incorporated in our pull-ring system thanks to their lipped ends. We have a wide portfolio of standard products – from manually adjustable throttle valves and pneumatic rotary actuators to electrically operated adjustable actuator. Other actuators and larger diameters are available on request. We reserve the right to alter design specifications.

 

Throttle valves without seal when closed:

  • Diameters of 60 – 400 mm
  • Hand-operated, made of powder-coated, galvanised and stainless steel
  • Pneumatically operated with a rotary actuator, and electrically operated with an electric motor, in powder-coated and stainless steel
  • Both shafts are sealed with an O-ring made of Viton and a conductive EPDM seal to discharge charges on the inner flap to the housing
  • Neither of the O-ring seals are in contact with the product
  • FOOD GRADE stainless steel version dually compliant for contact with food in accordance with EC 1935/2004 plus FDA
