The Maintenance of Gas Pressure Regulator

General Maintenance Instructions

Periodical maintenance is needed according to the general service conditions and the type and composition of the gaseous media. For maintenance all parts must be cleaned and subject to a thorough visual inspection. A visual inspection should not be omitted when the course of operation or functional tests have shown lack of regulating accuracy.

Particular care should be given to the checking of sealings and diaphragms, as well as of all carrying and moving parts. Damaged parts should be replaced by new ones. Diaphragms, valves sealings, circlips and o-rings must be kept available for maintenance works.

Special Maintenance Instructions

When loosening or screwing the nuts onto the valve rod of the regulating device, the valve rod must be held in position with a drift, thus preventing any rotation of the valve rod that would damage the compensating diaphragm.
