WARNING
!
Risk of personal injury due to preloaded springs.
Valves in combination with pneumatic actuators with preloaded springs are under ten-
sion. These control valves with SAMSON pneumatic actuators can be identied by the
long bolts protruding from the bottom of the actuator.
Î Before starting any work on the actuator, relieve the compression from the preload-
ed springs (see associated actuator documentation).
Risk of personal injury due to residual process medium in the valve.
While working on the valve, residual medium can ow out of the valve and, depending
on its properties, cause personal injury, e.g. (chemical) burns.
Î If possible, drain the process medium from the plant sections affected and from the
valve.
Î Wear protective clothing, safety gloves, respiratory protection and eye protection.
Exposure to hazardous substances poses a serious risk to health.
Certain lubricants and cleaning agents are classied as hazardous substances. These
substances have a special label and a material safety data sheet (MSDS) issued by the
manufacturer.
Î Make sure that an MSDS is available for any hazardous substance used. If neces-
sary, contact the manufacturer to obtain an MSDS.
Î Inform yourself about the hazardous substances and their correct handling.
Risk of personal injury due to incorrect operation, use or installation as a result of in-
formation on the valve being illegible.
Over time, markings, labels and nameplates on the valve may become covered with dirt
or become illegible in some other way. As a result, hazards may go unnoticed and the
necessary instructions not followed. There is a risk of personal injury.
Î Keep all relevant markings and inscriptions on the device in a constantly legible
state.
Î Immediately renew damaged, missing or incorrect nameplates or labels.
