Operating and Installation Instructions
Straight-through blow-down valves - STEVI
®
BBD 415
- The planner / construction company or operator is responsible for positioning and
installing the products.
- The valves are designed for application, not influenced from weather.
- For application outside or in adverse environments like corrosion-promoting conditions (sea
water, chemical vapours, etc.), special constructions or protective measures are recommended.
6.0 Putting the valve into operation
ATTENTION !
- Before putting the valve into operation, check the material, pressure,
temperature and direction of flow.
- All local safety instructions must be observed.
- Residues in piping or valves (dirt, weld beads, etc.) inevitably lead to leakage
and/or damage.
- Touching the valve when it is operating at high (> 50°C) or low (< 0°C) media
temperatures can cause injury.
Affix a warning notice or provide protective insulation as appropriate!
- The actuator can be used in the temperature range from -40°C to +100°C. At
temperatures below zero, it is important to ensure that the control air is dry,
while at high temperatures insulation against heat should be provided where
possible.
Before putting a new plant into operation or restarting a plant after repair or
modification, always make sure that:
- All work has been completed correctly!
- The valve is in the correct position for its function.
- The necessary safety devices have been attached.
