Installation & Operational Considerations
Before installing the product, blow out the piping to remove
any piping scraps, dirt, oil and scale.
Failure to do so may result in leakage at the seat due to foreign matter.
Do not remove the product from its box or protective covering
until just prior to installation.
The protective cover keeps damage causing foreign materials out of
the product.
CAUTION
Do not attempt to turn the handle past the full open or full closed
position.
Turning past these points may cause product malfunction or damage.
1. Product Description
BE8H series bellows sealed globe valves are used as stop valves. Stop valves are
designed only for shutting off and opening the path of flow.
Stem sealing is performed by a flexible bellows and an additional protecting gland.
Bellows sealed valves are provided with cast markings according to the requirements
of the PN-EN19 standard. The markings facilitate technical identification and contain:
・
nominal diameter DN (mm),
heat number
・
nominal pressure PN (bar),
・
body and bonnet material,
・
arrow indicating medium flow direction,
・
manufacturer,
・
heat number,
・
CE marking, for products subject to the
97/23/EC directive. CE marking starts from
DN32
2. Requirements for Maintenance Staff
The staff assigned to assembly, operation and maintenance tasks should be qualified
to carry out such jobs. If the valve is provided with mechanical actuators, the operating
manual of the actuator should be obeyed. During operation parts of the valve, for
example the handwheel, cover, or body, may become hot and the user should take
appropriate measures to prevent burns.
3. Transport and Storage
Transport and storage should be carried out at
temperatures between -20 and 65
°
C. Valves
should be protected against the influence of
external forces and destruction of the paint
layer as well. The aim of the paint layer is to
protect the valves against rust during transport
and storage. Valves should be kept in clean,
dry rooms and protected against the influence
of atmospheric conditions. A drying agent or
heating should be applied in damp rooms to
prevent condensate formation. The valves should be transported in such a way as to
avoid handwheel and valve stem damage.
Do not fit lifting devices to connecting holes or handwheel.
