Series 20 Pilots

• Mooney* Pilots
  Series 20*, 20H, and 20L The Series 20 Flowgrid* pilot is a reversible pressure-control regulator designed primarily for use as a  control pilot with unloading-type pilot systems for pressure-reducing (PRV), backpressure (BPV or Relief),  and differential-pressure (DPV) applications. The Series 20 pilot is designed for both gas and liquid applications. 

  Series 20  Brass construction with 3 to 450 psig (0.21 to 31 bar) control pressure range 

  Series 20H High pressure brass construction with a 200 to 900 psig (14 to 62 bar) control pressure range.

  Series 20S  Stainless steel construction with a 3 to 450 psig (0.21 to 31 bar) control pressure range.

  Series 20HS High pressure, stainless steel construction with a 200 to 900 psig (14 to 62 bar) control.   pressure range. 

  Series 20L-B Bronze construction with 5 i.w.c. to 8 psig (12 mbar to 0.55 bar) control pressure range. 

  Series 20L-A Aluminum construction with 5 i.w.c. to 8 psig (12 mbar to 0.55 bar) control pressure range.

  Other features include: 

  • Easy removal of the cartridge permits quick disassembly and assembly which is universal to all pilots.
  • Reversing valve stem converts pressure reducing to back pressure
  • Pressure boost feature
  • Ease of spring change
  • Cap cover protects adjusting screw
  • Sealed spring case
  • Flexibility with six different springs to cover pressure settings from 3 psi to 900 psig (0.21 to 62 bar)
  • Convert Series 20 to 20H with a high pressure diaphragm kit

  Applications:

  Mooney* Series 20 Relief Valve is a pilot-operated relief valve for D.O.T regulated (non-ASME) applications
