Aqua Environment Regulators
6000 PSI Back Pressure Regulator Model 211
General Information
Also known as a priority valve, the model 211 is a fully balanced, economical regulator. It serves a wide variety of uses, however it’s main use is on small compressors. The regulator will improve moisture separator efficiency and filter life as much as 450%. This is done by maintaining pressure in the separator and filter at 1800 PSI or more when tank pressure is lower. It has two outlet ports permitting attachment of a filling yoke and gauge directly to the regulator. This eliminates costly fittings.

| * Size - 3-1/2" x 1-1/2" x 1" |
Typical Applications
6000 PSI Reducing Regulator Model 415A
General Information
The model 415A is an economical, piston type, hand load regulator. It is available in three standard outlet pressure ranges of 0 to 400 PSI, 0 to 1500 PSI, and 0 to 5000 PSI. Other pressure ranges and a dome loading version are available on special order. Maximum inlet pressure for all ranges is 6000 PSI. The regulator seats are protected by a 20 micron filter. The regulator seat, poppet assembly and filter are contained in an easily replaced valve cartridge assembly pictured in the section drawing to the right. The low cost valve cartridge is factory preassembled. This cartridge assembly permits very easy and fast in-field servicing. All units are self venting. Unvented units can be provided on special order. An optional mounting bracket (Part No. 657) permits panel surface. The unit is exceptionally rugged and insensitive to inlet contaminates. This, in addition to it’s low cost has resulted in it’s extensive use in fuel applications such as air and gas fill stations.

Typical Applications
6000 PSI High Flow Back Pressure Regulator Model 635
General Information
Also known as a priority valve, the model 635 is a fully balanced economical regulator. It is similar to our model 211 regulator but it is capable of much higher flow rates. It’s primary use is on compressors to maintain back pressure on filters and separators thus improving their efficiency as much as 1000%. The stainless steel metal to metal seat is designed to be self cleaning. It maintains constant back pressure (set pressure) independent of outlet pressure. When outlet pressure (such as in a tank being filled) reaches set pressure the regulator opens fully permitting unrestricted flow. Normally the valve is set for back pressures of 1500 to 6000 PSI. However, it can be set for pressures as low as 150 PSI. Lighter than standard springs can be ordered to improve low pressure operation.

| Set pressure : 1800 PSI nominal (adj. 150 to 6000 PSI) |
| Flow capacity —2 to 300 SCFM |
| Materials — anodized aluminum body, bronze, stainless |
| Leakage -- Zero external; about 0.1 SCFM internal |
| Ports — 1/2" female pipe thread |
| Size — 5.3" x 2" x 1.5" |

Typical Applications
6000 PSI High Flow Reducing Regulator Model 873
General Information
The model 873 is a piston type hand 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 permitting very easy in field servicing. The low cost poppet cartridge (pictured on the opposite side of this sheet) is factory preassembled. It contains the more critical valving elements of the regulator thus eliminating in-field servicing problems. The regulator is self venting but is optionally available without the vent. This regulator design was developed for gas mixers for commercial diving where high flow, very precise pressure control and high reliability are needed. They have served this application for many years. It is available with different size sensing pistons resulting in a complete range of outlet pressures. A highly sensitive dome loaded version rated to 6000 PSI is also available.
| Technical Specifications |
| Rated pressure - 6000 PSI (40 MPa) |
| Inlet : 1/4" male NPT |
| Materials — anodized aluminum, Buna N seals |
| Model 708 seals on 4500 PSI cylinder valves but vents on lower pressure cylinder |
| Model 835 seals on either type of cylinder |
