Safely isolates July 1st 2008 Spirax Sarco says steam and fluid
systems can be upgraded quickly
to allow safer, more cost-effective
maintenance procedures with a
space-saving SafeBloc double
block and bleed (DBB3) valve.
Comprising two isolation valves
and a bleed port in a compact
assembly, it is easy to install into
the space left by a single isolation
valve, without pipework changes.
The technology offers zero gland
leakage, while ensuring tight shutoff
conforming to DIN 3230 BO1
and ISO 5208 Rate A
specifications. The unit's internal
flow path offers the same minimal
pressure drop as conventional
arrangements. Double block and
bleed enables a section of plant to
be safely isolated for maintenance
without having to shut down the
entire system. More articles from Spirax Sarco Ltd: |
