2.1.2 Pressure Regulators
Maintain pressure regulators in good condition. Never use oil on pressure
regulators.
Pressurization systems that leak should be repaired or replaced.
Gauges, fittings and hoses should be kept in good condition and leaks should be
corrected.
Periodically test the safety relief valves on the pressurization manifolds to
verify they will relieve if excessive pressure should occur. Never plug or bypass
these safety valves.
When pressurizing the cell, always make sure that the regulator is closed (i.e.,
Tee screw backed all the way out, counterclockwise). Then open the supply
pressure, and adjust the regulator.
Do
NOT
attempt to pressurize higher than 100 psi (694 kPa).
Follow the pressurizing procedures in Section 4.
When depressurizing, first shut off the supply pressure. Then bleed the system
of pressure, and back out the regulator Tee screw (turn counterclockwise),
following the procedures in Section 4.
