3.0 Storage and transport
ATTENTION !
- Protect against external force (like impact, vibration, etc.).
- Valve mountings such as actuators, handwheels, hoods must not be used to
take external forces, e.g. they are not designed for use as climbing aids, or as
connecting points for lifting gear.
- Suitable materials handling and lifting equipment should be used.
See catalog sheet for weights.
- At -20°C to +65°C.
- The paint is a base coat to protect against corrosion during transportation and storage. Do
not damage paint protection.
4.0 Description
4.1 Scope of applications
Valves are used for „shut-off and/or throttling of media“.
ATTENTION !
- Refer to the data sheet for applications, limits on use and possibilities.
- Certain media require or preclude the use of special materials.
- The valves are designed for standard operating conditions. If conditions exceed
these requirements, e.g. aggressive or abrasive media, the operator should
state the higher requirements when ordering.
- You must state whether the valves are to be used in an explosive atmosphere
(ATEX) at ordering.
Special design!
The information complies to the Pressure Equipment Directive 97/23/EC and Machine
Guideline 2006/42 EC.
It is the responsibility of the machine planner to ensure compliance.
The special markings on the valve must be taken into account.
Refer to the catalogue sheet to see which materials are used in standard versions.
Please contact the supplier or the manufacturer if you have any questions.

4.2 Operating principles
The valve is closed by turning the hand wheel clockwise (valve plug/seating function).
ATTENTION !
- Do not use tools to increase the torque on the hand wheel.
- The necessary fire-protection measures depend on the medium and must be
specified by the operator.
The valve stem is sealed by stuffing box.
Tighten the stuffing box if required.
The stopf valves are especially suitable for actuation by pneumatic or electrical actuators.
ATTENTION !
- The drive shaft is partially open and there is a crushing hazard!
