Model 143 Sizing Tool
Service regulator for residential meter sets and small commercial and industrial loads. Available with an internal relief valve or a low-pressure cut-off. New orifices coming soon!
Note: The tool cannot size an internal relief valve above 2 psi set point. If you ask for over-pressure protection with a higher outlet, the tool will report that it cannot size the application. Without over-pressure protection the full range up to 6 psi is available.
