Aqua Environment 1120-NV 1120 Series Hand Load Reducing Regulator 1/4" NPT 0-5000 PSI Out Non-Vented Single Outlet

The model 1120 is a small, piston type, hand load regulator available in an outlet pressure range of 0 to 5000 PSI. Functionally it is similar to model 415 5000 regulator but has only a single inlet and outlet port. It is available with a hex head adjusting bolt and lock nut for single set pressure use or with the same adjusting hand knob as used on the model 415 regulator. It can be panel mounted using either the upper 1.25" threaded section and lock nuts (part number 952) or the lower 1 inch jam nut. It uses an unbalanced poppet design for ruggedness and simplicity. There is a small variation of control pressure with changing inlet pressure as noted in the specifications. A 20 to 30 micron filter in the poppet cartridge prevents damage by contaminants.

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 at the bottom of the regulator as shown. The outlet is at the side. These may be used to mount the regulator through a 1.25" panel hole. Optionally the regulator can be mounted using the 1 inch jam nut and body flange shown near the bottom of the regulator. The regulator is NOT shipped oxygen clean and should NOT be used for oxygen service as provided. AS WITH ANY REGULATOR, A RELIEF VALVE SET SLIGHTLY ABOVE THE MAXIMUM DESIRED CONTROL PRESSURE SHOULD BE INSTALLED ON THE OUTLET SIDE.

Maintenance and repair caution

As with any regulator or valve, particulates or moisture can plug or freeze the internal filter or valve seat. This can occur when upstream dryers are not changed or remain unused for long periods allowing corrosion materials to accumulate. In critical applications where it is important not to lose flow, a larger particulate filter should be used upstream.
