Model 873 High Flow Reducing Regulator 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 below) is factory preassembled. It contains the more critical valving elements or 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 over forty years. It is available with different size sensing pistons resulting in a complete range of outlet pressures.

Model 873-D, a highly sensitive dome loaded version rated to 6000 PSI is also available.
