Aqua Environment 1092-50 1092 Series High Flow Economical Dome Loaded Reducing Regulator Non-Vented 1/4" MNPT 50-6000 PSI

The model 1092 is an inexpensive, compact, highly accurate dome load regulator. It is non venting. It uses the same reliable valve cartridge used in the 873 high flow regulators. This regulator is about four times as accurate as the 873 spring loaded regulators but requires a separate source of control pressure to the dome. The standard bias is about 120 PSI open. The regulator with bias is sometimes used for cascade filling systems. It's primary function is control of cascade systems used for such purposes as filling breathing air cylinders and vehicle CNG (compressed natural gas) tanks.

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 the male thread at the bottom of the valve and the outlet is the female thread at the side of the valve. The dome load port is the male thread at the top, center. The one inch thread at the bottom of the valve can be used to mount the valve through a one inch hole in a panel or mounting plate provided by the user. Actuating or dome pressure as well as inlet fluid can be any non corrosive gas or liquid at any pressure up to 6000 PSI. 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 up stream 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.
