Buffer tank Pressure Relief Valve

This valve is provided to supplement the pressure regulator for rapid relief
of pressure above the regulator set point.

Operation

Operation is automatic. The valve is factory set to start relief at 70 psi and
can be field adjusted by a qualified technician as required.

Maintenance

There is no normal operating maintenance; however, in the event of an
overfill condition and liquid fouls the valve, it should be replaced.
