Aqua Environment Regulators

The 873 series regulator is a piston-type hand loaded 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 is factory pre-assembled. It contains the more critical valve 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 mixtures 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.
