Pneumatic VP TYPE

Features:

  • Double acting (open / close by air) or spring return (either air close or air open and return to rest position by springs).
  • Fully made in stainless materials, resistant to most of corrosive agents.
  • Air, water, oil or other non-corrosive fluid feed, at a maximum pressure of 8 bars.
  • 90º turn (quarter turn) with a 2º tolerance in opening / close operation.
  • Temperature range from –32ºC to +90ºC under normal working conditions (intermittent peaks of –43ºC and 120ºC).
  • Constant and high torque output.
  • Visual position indicator.
  • Can be fitted parallel or perpendicular to the pipe.
  • Manual device for Emergency Operation (double acting only).

Options:

  • 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 P20).
  • Manual operation by disengaging gearbox.
  • Regulating opening limit devices.
  • AISI 316 stainless steel actuator, valid for marine and under water installations and up to 10-bar feed (steel inside for up to 15 bar feed as option).
  • Actuator for high temperature (up to 265ºC +- 5ºC), up to 10 bars feed.
  • Actuator with thermoplastic housing.
  • Polyamide actuator.
