Double Acting Pneumatic Actuator 3400

Application

General use : Pulp production, water, water treatment, waste water, chemical industry (powder or crystalizing products), win-producing, pulverized products (cement work, pneumatic transport, stocking).

General Characteristics

  • Function ON/OFF or regulation
  • Wafer threaded mounting ISO PN10
  • Unidirectional tightness, direction indication thanks to the arrow on the body
  • Small retention zone: the gate is guided in the body and has little clearance
  • glad assembly: packing and O-ring (same material as seat joint) to assure the elasticity and decrease the operating force
  • Small head loss
  • Possibility to regulate thick fluids the adaption of a diaphragm ring.
