Aqua Environment 873-D-NV-NF-L 873-D Series High Flow Dome Loaded Reducing Regulator High 6000 PSI Low Temperature Non-Filtered Non-Vented

The model 873-dome is a piston type dome loading regulator. It utilizes a balanced poppet design for high flow and minimum effect of inlet pressure on outlet pressure. The poppet assembly is contained in a cartridge with internal filtration for easy in-field changing. The regulator is self venting but is optionally available without the vent.

Features:

• High Flow Dome Loaded Reducing Regulator
• High Accuracy
• 1/2 in. NPT outlet
• 1/4 in. NPT inlet
• 0 to 6000 psi outlet pressure
• Non-vented
• Non-filtered
• Low Temperature (-60ºF)

Typical Application:

• Operation of high flow, low pressure equipment such as sirens from high pressure air tanks. Here use of high pressure air eliminates dependency on electrical power in an emergency.
• Component testing
• Air tank fill stations
• Fire fighting air systems
• Instrumentation and calibration panels
• Process industry control
• Shipboard and oft shore air and gas control
• Aircraft service equipment
• Electronic industry rare gas flow
• Vehicle CNG stations
• Precision gas mixing equipment

Installation

Use a suitable pipe thread sealant such as teflon tape on inlet and outlet threads. Avoid over torquing pipe thread. Normal torque applied with a 6 or 8 inch long wrench is ample. Use ample teflon tape - 3 or 4 turns, not 1 or 2 turns. The inlet is on the left when facing the adjusting knob with the two gage ports upward. The regulator is NOT shipped oxygen clean and should NOT be used for oxygen service as provided.
