The Cash Acme E-3 Pressure Regulating Valve automatically reduces a high inlet pressure to a lower delivery pressure and maintains the lower pressure within acceptable limits. It provides substantially higher capacity and closer regulation for more demanding and higher quality installations. The E-3 incorporates a yoke-type design, allowing the regulator to close against the inlet pressure and provide quieter operation under wide and varying flow conditions.

The E-3 is designed for use where supply line inlet pressure does not exceed 300 psi and is suitable for either cold or hot (to 180°F) water service for a variety of applications. Standard factory outlet setting is 45 psi, but other settings are available.
