The need to control process and vent valves from a remote location makes air operated (pneumatic) valves a vital component to many process applications.

All MAN Series needle valves with MPI™ connections are available with Fail Open (-FO) or Fail Closed (-FC) Piston Type Actuators. Four sizes of air actuators (Medium, Heavy, Extra Heavy-Single Stage, and Extra Heavy-Two Stage) are offered to meet the service requirements of Parker MAN Series Needle Valves. Both Fail Closed (normally closed) and

Features and Benefits

  • Fail Open or Fail Close with spring return or Dual Acting (air controls both directions)
  • Piston actuator sizing incorporates maximum allowable air pressure of 100 psi
  • Yoke design for separation of process and air controls
  • Stem Position Indicator is standard
  • Anodized Aluminum Housing (for corrosion and wear resistance)
  • -20°F (-29°C) to 200°F (93°C) ambient temperature range (for operation below 30°F (-1°C) dry air must be used and heat tracing is recommended)
  • Remote position indication options available
  • High actuator cycle life
  • Ease of stem replacement
  • 1/8" NPT air inlet connection standard except Extra Heavy Duty has 3/8" NPT
  • Remote On-Off

    Parker MAN series air-operated needle valves (FC – Fail Close or FO – Fail Open) can be controlled by a 3-way manual air valve or by a low pressure solenoid valve (supplied by others). These can be actuated manually or remotely depending on application requirements.

    Fail Safe control of the actuators is possible through the use of 3-way manual or solenoid operated valve placed in the pneumatic control line to either Fail Open or Fail Closed actuator.

    Remote operation increases personnel safety by eliminating the requirement to move adjacent to High Pressure Piping.

    Please note: Depending on selection of actuator, some applications will require pressure on valve to assist in opening against actuator springs.
