A Unique Plug Valve Program
Double Block and Bleed Valve type 55 programme
All DBB valves from Christensen are designed with
the patented CCR System which avoit overpressure
in the inner cavities between the 2 plugs.
C H R I S T E N S E N
Cavity Relief System
All DBB valves are designed with a bore going from
the body sealing surface against the diaphragm, to the
port outside of each plug. Normally this bore is kept
closed by the pressure of the bottom cover, if the
pressure in the cavity increases more than normal, it
will automatically open to the bore via the diaphram .

Taper Plug Valves
Pressure balanced Design
Robust and compact construction
High quality
Self-protecting seating surfaces as abrasive
Impurities are wiped off when the plug turns
Moving parts: plug and stem (stem blowout proof)
Metal to Metal sealing
Fire-safe design
The plug is individually matched to the body
Low torque values
Higher port area

A Unique Plug Valve Program
Metal to metal sealing
(perfect match between body and plug )
Seating area
Up to 30 dgr on each side
Fully protected by body in open
position
Never exposed 100% to media
during open /close

Unique Seal properties
• 3 independent seals

Your desicion
High investment
Low investment*
or
low operation costs
high operation costs
• Often low valve price = lower CV value. ( All BCH valves have large cm2 port areas )
• Often low valve price = Higher torque`s ( BA ) on the valves
• Often low price = shorter technical life cycle
