media when working near or on the valve

Revisions and other modifications
Revisions, conversions or other modifications to the product are not authorized by SAMSON.
They are performed at the user‘s own risk and may lead to safety hazards. Furthermore, the
control valve may no longer meet the requirements for its intended use.
Safety devices
Upon supply air or control signal failure, the valve moves to its fail-safe position (see sec-
tion 3.1). The fail-safe action of the actuator is the same as its direction of action and is spec-
ified on the nameplate of SAMSON actuators (see actuator documentation).
Warning against residual hazards
To avoid personal injury or property damage, plant operators and operating personnel must
prevent hazards that could be caused in the control valve by the process medium, the operat -
ing pressure, the signal pressure or by moving parts by taking appropriate precautions. They
must observe all hazard statements, warning and caution notes in these mounting and oper -
ating instructions, especially for installation, start-up and maintenance.
Responsibilities of the operator
The operator is responsible for proper operation and compliance with the safety regulations.
Operators are obliged to provide these mounting and operating instructions to the operating
personnel and to instruct them in proper operation. Furthermore, operators must ensure that
operating personnel or third persons are not exposed to any danger.
Responsibilities of operating personnel
Operating personnel must read and understand these mounting and operating instructions as
well as the specified hazard statements, warning and caution notes. Furthermore, the operat-
ing personnel must be familiar with the applicable health, safety and accident prevention
regulations and comply with them.
