Pneumatic VCH TYPE

Features:

  • Double acting (open / close operation by air) or spring return (either air close or air open and return to rest position by springs).
  • Heavy aluminium made, resistant to most of corrosive agents.
  • Clean air (dry or lubricated) oil or non-corrosive gas feed at maximum pressure of de 10 bars.
  • 90º turn (quarter turn) with a 4º tolerance in open / close operation.
  • Temperature range from –20ºC to +80ºC under normal working conditions.
  • Constant and high torque output.
  • Visual position indicator.
  • Regulating limit stops in opening and close.
  • Lubrication guaranteed for a minimum of 1.000.000 operations.
  • Can be fitted parallel or perpendicular to the pipe.
  • Manual device for Emergency Operation (double acting only).

Options:

  • Chemical Nickel or Teflon coating for body and covers.
  • Regulating limit switch box (electromechanical, inductive, magnetic or pneumatic) with NAMUR (VDI/VDE-3845) standard connection.
  • Inductive or magnetic detectors.
  • Box with built-in limit switches and solenoid valve.
  • NAMUR solenoid valves (3-way for spring return and 5-way for double acting.
  • Antideflagration solenoid valves.
  • Pneumatic (3-15 p.s.i.) or electropneumatic (4-20 mA) positioners.
  • Direct manual override facility (double acting only up to CH100).
  • Manual operation by disengaging gearbox.
