Regulators

Monnier catalogs a wide variety of fluid-air regulators to provide a constant air line pressure. Standard line regulators are suitable for optimal pressure ranges from 0-10 psi to 20-250 psi and come in 1/8″to 1-1/2″ line sizes. When space is at a premium, try Monnier’s subminiature regulators specifically designed for low-volume air flow and dead end service.
To complement standard regulators, Monnier can fit regulators with:
- Built-in check valves
- Valve sandwich block and manifold mounted air-line regulators
- Pilot-operated pressure regulators.

Float Drains
The Monnier Float Drain is an ideal, low-maintenance drain for airline legs and air filters. The Float Drain has the following characteristics:
- Typically open
- Pilot operated valve rated for 10-250 psi and 175° F
- String on/off action – closed by system air pressure
- inlet sizes from ¼” – ½”
Impulse Drains
Monnier Impulse Drains are the simple solution for removing excess line liquid. If necessary, replacement of the Impulse Drain takes less than 1 minute.
- Only one moving part – no float, levers or pilot mechanisms
- Gum & corrosion resistant
- Actuated by a 10 percent decay in pressure caused by cycling of valves, tools or compressors
Air/Oil Reservoirs
Designed to be placed between the valve and cylinder in a
pneumatic circuit, Monnier’s Air/Oil reservoirs provide the
predictable, even cylinder actuation of a hydraulic system
in a low cost pneumatic circuit.
Compressed air enters the top inlet port and forces the
hydraulic fluid out of the reservoir and into the downstream
cylinder. Pressure is maintained at a 1:1 ratio.
- Available with aluminum or polycarbonate bowls
- ‘L’ brackets and stud mount brackets available
- Available in capacities from 12 to 70 cubic inches (6.65 to 40.37 ounces)
