Installation
Refrigerants
Applicable to all common non-ammable
refrigerants, including R717 and non-
corrosive gases/liquids dependent on
sealing material compatability.
Special types required for ammable
hydrocarbones. The valve is only
recommended for use in closed circuits. For
further information please contact Danfoss.
Temperature range
Temperature range for BSV used as an
external safety relief valve:
–30/+100°C (–22/+212°F)
Temperature range for BSV used as a pilot
valve for POV:
–50/+100°C (–58/+212°F)
Note:
For temperatures below –30°C (–22°F), the
valve may not re-seat to a 100% gas
tightness when activated.
Pressure range
The valve is designed for a max. working
pressure of 25 bar g (362 psi g). Danfoss
Industrial Refrigeration A/S is supplying
safety valves adjusted for a certain pressure
(indicated on the ID-plate) and sealed.
Danfoss Industrial Refrigeration guarantees
correct pressure as long as the seal remains
unbroken.
Installation
The valve should be installed with the
spring housing upwards (g. 1).
By mounting of the safety valve it is
important to avoid the inuence of thermic
and dynamic stress (vibrations) (g. 2).
The valve is designed to withstand a high
internal pressure. However, the piping
system should be designed to avoid liquid
traps and reduce the risk of hydraulic
pressure caused by thermal expansion. It
must be ensured that the valve is protected
from pressure transients like “liquid
hammer in the system.
Welding
If welding ttings are applied, these
should be dismounted during the welding
process (g. 3). Only materials and welding
methods, compatible with the ange
material, must be welded to the ange.
Avoid welding debris and dirt in the
threads of the housing and pipes.
Assembly
Remove welding slag and dirt from tubes
and housing before the valve is mounted.
Mount the valve as shown in g. 4.
Colours and identication
The valves are Zinc-Chromated in the
factory. If further corrosion protection
is required, it can be painted. Precise
identication of the valve is made via the
ID label on the valve housing.
In cases of doubt, please contact Danfoss.
Danfoss accepts no responsibility for
errors and omissions. Danfoss Industrial
Refrigeration reserves the right to make
changes to products and specications
without prior notice.

安装方向
制冷剂
适用于各种不可燃制冷剂,包括氨和其他
无腐蚀性的气体\液体工质(需考虑密封
介质的兼容性)。
不推荐将其应用在易燃易爆的碳氢制冷剂
上。阀门应使用在密封的制冷系统内部。
如需了解更多详情信息请联系丹佛斯。
度范围
作为外部安全泄压阀使用的 BSV 的温度
范围:
–30/+100°C (–22/+212°F)
作为 POV 导阀使用的 BSV 的温度范围:
-50/+100° C ( - 58/+212° F )
注意:
温度低于 - 30° C ( - 22° F ) 时,阀门开启后
不能保证 100% 回座气密性。
压力范围
阀门最大设计工作压力为 25 bar
362 psi g)。丹佛斯工业制冷提供设定
好压力的安全阀(标记在 ID 牌上)并且
铅封。
只要不破坏铅封,丹佛斯即可保证正确的
设定压力。
安装
为保证安全阀的正常工作,阀门的弹簧阀
体必须竖直向上安装(图 1)。
安装安全阀时,避免热和动应力(振动)
的影响(图 2)。
BSV 系列安全阀的设计可以承受很高的内
部压力。尽管如此,管路系统的设计也必
须避免有存液弯,防止系统出现因热膨胀
导致的过高压力而损坏管路。管路的设计
应考虑对系统中出现瞬时“液击”现象的
有效防护。
焊接
焊接接头过程中,接头必须从阀门上拆下
焊接(图 3)。焊接过程中,需要保证焊
料和焊接方法适用于阀体或法兰的材质,
选择合适的焊料和正确的焊接方法。
焊接后阀体内需要认真清理,确保安装前
焊渣已清理干净,避免焊接杂质和污垢进
入管道及螺纹。
装配
在组装阀之前,清除阀体和管道里的焊渣
和污垢。如图 4 所示安装阀门。
颜色和识
BSV 系列安全阀已在出厂前进行了镀锌铬
防锈处理。然而此处理没有覆盖到阀门的
焊接连接部分。如果需要做进一步防腐蚀
保护,可以为阀门喷漆处理。阀门的精确
标识位于阀体的信息识别(ID)标签上。
如有任何疑问,请联系丹佛斯当地办事
处。丹佛斯对错误或疏漏概不负责。丹佛
斯工业制冷部门保留在不预先通知的情况
下变更产品和规格的权利。
