Functional descriptionFunctions according to the force compari-son principle between the force of:- the adjustable setpoint spring- thedifferentialpressureatthework-
ing diaphragm- the force due to weight of the moving
partsThe adjustable spring acts with the force due to weight of the moving parts. The output pressure is adjusted depending on the pretension of the adjustable spring and the installation position.
Do not route condensate from lines into the pressure
regulator.Protect the pressure regulator from fouling by means of a suit-able dirt trap.
Do not apply combustion gas or combustion gas air
mixtures to the installation cham-ber of the adjustable spring.
InstructionsGas-conveying lines, pulse and con-nection lines must be made of steel and at least PN 1, DN 6. The lines must be resistant to thermal, chemical and mechanical loads. The lines must be durable and resistant to deformation and cracks.

Equipment preselection, blocked pressure regulatorsYou can preselect the nominal diam-eterusingthevolumetricflowpressuredrop characteristic of the pressure regulators in mechanically open state. The pressure drop between input pres-
sure p1 and regulator output pressure p2 in connection with the maximum volu-metricflowVmax determine the nominal width of the pressure regulator. The operatingpointdescribedby∆pmin and Vmax is left of the nominal width of the pressure regulator to be selected.
The pressure drop over blocked pres-sure regulators is described by the "mechanically open" characteristic.The final determination is performedaccordingtothedimensionspecifiedby the gas appliance manufacturer.
