Nitrogen Regulator - Dual Gauge - Nitro Beer - Cold Brew Coffee - MK4 - Type 50 - N2

This is the only regulator you'll ever need to buy for the perfect nitrogen stout / nitro coffee / espresso Martini cocktail setup. With a large body and precision diaphragm, this regulator provides high flow rates and very accurate adjustments in both PSI and KPA.
The MK4 Nitrogen regulator provides reliable gas control. It has a large body with high flow rates and has a precision diaphragm allowing accurate adjustments in psi, bar and kpa, with the easy to use adjustment knob.

This  regulator with Type 50 fitting is perfect for any stout, porter or nitro beer, Coffee or non-carbonated cocktail dispensing system. Compatible with larger commercial Nitrogen Cylinders, perfect for cafe's or bars doing high volumes.

A common problem with regulators sold on the market was contamination could occur through the seat and cap assembly within the regulator due to an old design. This issue has now been solved with a 2nd sintered filter in the underside of the seat assembly, inside the regulator, to filter contaminants.

You will need a nitrogen cylinder with type 50 valve to use this reg (not a co2 cylinder with type 30 valve)

New and improved regulator features:

  • Steel Gauges made from thicker steel
  • Gauges read in kPa, Bar and PSI
  • New Colour Coded pressure release valves (PRV) allowing different pressure levels for safety.
  • M6 Mounting Holes for mounting options.
  • 0-50 PSI recommended working pressure (higher pressure gauges and PRV can be fitted to make this model go up to 100 PSI)
  • Green (65psi) PRV installed by default. Lower (35psi) and higher (100psi ) pressure relief valves are available (sold separately).
  • 1/4" MFL outlet (uses same swivel nut & barb as MFL ball lock disconnects & also fits our MFL 8mm push fittings)
  • Default to work with Nitrogen or Nitrogen/C02 mix - Type 50 stem

This regulator has been designed so that the whole seat and seat cap assembly are manufactured as a fully encapsulated part. This adds to the reliability and in the case that the regulator is eventually opened up for servicing it reduces the chance of this assembly becoming contaminated by the service agent. This further improves reliability.

Output Pressure Gauge: 0-100 PSI
Tank Pressure Gauge: 0-3000 PSI
Outlet: MFL with Barbed Swivel Nut
Effective Working Pressure: 0-50 PSI

Controls high pressure N2 from a cylinder down to pressures usable in a beer or coffee or cocktail keg or other situations where low pressure is needed.

  • Hi can I purchase off you then pick up? Does the regulator allow to control the flow of gas ?

    Pickup is all ok - Can let you know once purchased.  No Flow Meter on these - just PSI
