Malfunctions

Table 10:

Troubleshooting

Malfunction

Possible reasons

Recommended action

Downstream pressure

drops below the

adjusted set point.

Regulator installed against the flow.

Install the regulator so that the direction of flow

matches the direction indicated by the arrow on

the body.

Regulator or K

coefficient too

small

Check the sizing.

Change K

coefficient, if necessary or

install a different sized regulator.

Contact SAMSON's After-sales Service

department.

Pressure tapped at the wrong place

(regulator with external control line).

Reconnect the control line at another point.

Do not connect the control line at pipe bends or

necks.

Foreign particles blocking the plug

Remove foreign particles.

Replace damaged parts.

Contact SAMSON's After-sales Service

department.

Compensation chamber in the wrong

position or too small (with steam).

Reconnect compensation chamber at a different

place or replace it (see section 7.7).

Control line blocked

Clean the control line and screw fittings.

Strainer blocked.

Clean strainer.

Jerky control

response

Increased friction, e.g. due to foreign

particles between seat and plug.

Remove foreign particles.

Replace damaged parts.

Contact SAMSON's After-sales Service

department.

Loud noises

High flow velocity, cavitation.

Check the sizing.

Install larger regulator, if necessary.

Install flow divider with gases and steam.

Leakage at the

actuator.

Defective operating diaphragm/bel-

lows.

Replace damaged diaphragm/bellows.

Leakage at the bellows

seal.

Defective bellows seal

Replace bellows seal.

Contact SAMSON's After-sales Service

department.

Red mark appears at

the diaphragm rupture

indicator (actuator

with two diaphragms).

Defective operating diaphragm

Replace damaged operating diaphragm.
