1.3.4 Valves for Oxygen
Valves for oxygen (O2) have additional markings:
•
"Oil and grease-free, suitable for oxygen"
1.4 Condition on delivery, transport and sto-
rage
The valves are delivered with an outer coating, sealed with
protective caps, and in an open position.
Valves made of stainless steel are not coated.
The valve must be stored dry in its original pack-
aging and/or sealed with protective caps.
Sealing surfaces and threads in particular must not be
damaged mechanically or through any other factors.
Valves for oxygen are delivered sealed in film. Shipping and
storage must be carried out in such a way that the film does
not become damaged. Only undamaged transport film
guarantees freedom from oil and grease as packed after
manufacture.
Lifting equipment must be fixed to the valve body.
The coating, handwheel and accessory parts must not be-
come damaged by the lifting equipment being hooked on.
Lifting equipment must not be hooked to handwheel or
valve spindle.
ACCIDENT HAZARD! DAMAGE
to the prod-
uct!
The valves should be stored in closed, dry rooms on a firm
clean base.
2. Product
2.1. Proper Use
The valves have been designed exclusively for installation
into a pipeline system to block off or guide through media.
A valve may not be used if its permissible pressure/
temperature range (="rating") is not sufficient for the
operating conditions. The permitted values can be found
on the valve name plate or the product data sheet. Special
approval is required from KROMBACH for use of the valve
outside these values.
Disregarding this regulation can lead to danger to life
and limbs and cause damage in the pipeline system.
It must be guaranteed that the parts of the valve that come
into contact with the media are made of materials suitable
for the media used. KROMBACH will not accept liability for
any damage caused by corrosion through aggressive media.
Disregarding this regulation can lead to danger to life
and limbs and cause damage in the pipeline system.
For valves that are used as an end valve:
During normal operation, in particular with gaseous, hot
and/or hazardous media,
a blind flange or cap must be
fitted to the open connection
or (only suitable for short-
term use!) the valve must be safely locked in the "CLOSED"
position.
If the valve has to be opened as an end valve in a
pressurised line, this must be done extremely carefully so
that the
medium sprayed
out does not cause any damage.
Be careful when closing such a valve: Danger of crushing
between housing and ball!
If a valve has to be removed from a pipeline:
Medium can escape from the pipeline or the valve.
In the case of media that can be harmful to health or are
hazardous, the pipeline has to be completely emptied
before the valve is removed. Be careful of
residue that can
flow out of dead spaces in the valve or the pipeline or
have remained in the valve (under pressure).
