REGULATORS FOR SPECIFIC APPLICATIONS
AG3840, AG3900 Series
High Delivery Pressure Regulators
These single-stage, piston sensed, pressure regulators are designed for applications requiring very high delivery pressures (up to 2500 psig). Constructed of either brass or stainless steel, they are available in both cylinder and line configurations.
These regulators are commonly used in high pressure sampling systems, calibration systems, aircraft service and test stand equipment.
Standard Features
- High Delivery Pressures up to 2500 psig.
- Piston Sensor Design ensures safe reliable service.
- Filter traps foreign matter, extends regulator life and reduces maintenance.
- Diaphragm Seal Outlet Valve provides for on/off flow control (cylinder regulators only).
- 1/16" NPTF Bonnet Vent Port allows bonnet to be connected to a vent line or disposal system as a precaution in the unlikely event of a diaphragm failure
Optional Features
- Mounting Ring permits regulator to be panel mounted
- Captured Venting Configuration provides 1/16" NPTF vent port and stem packing allowing for complete capturing of bonnet when connected to a vent line or disposal system.
