26 EB 8091-1 ENMounting and start-up3. Lift the valve to the site of installation.Observe the flow direction through thevalve. The arrow on the valve indicatesthe direction of flow.4. Make sure that the correct gaskets areused on the end connections.5. Bolt the pipe to the valve free of stress.6. Depending on the field of application,allow the valve to cool down or heat upto reach ambient temperature beforestart up.7. Slowly open the shut-off valve in thepipeline after the valve has been in-stalled.Risk of valve damage due to a sudden pres-sure increase and resulting high flow veloci-ties.Slowly open the shut-off valve in the pipelineduring start-up.8. Check the valve to ensure it functionsproperly.Version with welding ends1. Proceed as described for Version withfemale thread or flanges (steps 1 to 3).2. Completely retract the actuator stem toprotect the plug from sparks during weld-ing.3. Weld the valve free of stress into thepipeline.4. Proceed as described for Version with fe-male thread or flanges (steps 6 to 8).5.3 Quick checkSAMSON valves are delivered ready foruse. To test the valve's ability to function, thefollowing quick checks can be performed:Tight shut-off1. Close the valve.2. Slowly open the shut-off valve in thepipeline.Risk of valve damage due to a sudden pres-sure increase and resulting high flow veloci-ties.Slowly open the shut-off valve in the pipelineduring start-up.3. Check the valve for leakage (visual in-spection).Travel motionThe movement of the actuator stem must belinear and smooth.Î Open and close the valve, observing themovement of the actuator stem.Î Apply the maximum and minimum con-trol signals to check the end positions ofthe valve.Î Check the travel reading at the travel in-dicator scale.Fail-safe positionÎ Shut off the signal pressure line.Î Check whether the valve moves to thefail-safe position.NOTICE!NOTICE!
