Parker MAN series needle valves with MPI™ tube connections are designed for multi-turn control of liquid or gas media with regulation or shutoff options for pressures up to 15,000 psi. This Double Ferrule connection delivers fast, easy make-up and reliable bubble-tight performance in either liquid or gas service. Valves are built for MPI™ tube sizes from 1/4" to 1" and include five different body patterns providing many control options.

Our Parker MAN Series valves can be used, depending on ASME Code Selected safety factor, up to 15,000 psi/1035 bar. However, when using Pneumatically Actuated Valves, this requires the user to make an orifice size selection with our largest three sizes of valves for the highest operating range of the actuator possible.

NOTE:
  • Replace "B" in part number with "R" for Regulating Stem.
  • For 2507 Super Duplex option, replace -SS with -2507.
  • XF Ferrules are required for 3/4" and 1" 316 SS or 2507 Super Duplex Tubing.
  • Dimensions in inches are for reference only, subject to change.

    Parker MPI™ Connection Benefits

    		 N/A MPI™ Connections are designed for both liquids and gases. They can be used on MPI™ 1/8th Hard tubing, Autoclave Engineers Medium Pressure Tubing, or Thick Wall Instrumentation Tubing in both 316 SS and 2507 Super Duplex materials.

  • Suparcase® Technology creates a Corrosion Resistant Ferrule set for a strong, mechanical hold
  • Double Ferrule design is proven but not interchangeable with standard tube fittings
  • Longer Thread Engagement improves resistance to pressure and load on ferrules
  • Molybdenum Disulfide Coated Gland Nut prevents galling and makes assembly easier.
