Mooney-Series 20 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
