Kaneko Sangyo GU-25 Series Gas Seal Unit

Manufactuer: Kaneko Sangyo
Model: GU-25 Series

Summary

To store powder, liquid pure water, ultrapure water, chemicals, pharmaceuticals, petroleum products, and food, essential for pharmaceutical manufacturing and the semiconductor industry, a method encapsulates these substances with an inert gas. This process prevents alterations caused by exposure to air.I

Gas seal unit, the set pressure has two types intended for nitrogen gas reservoir or the like, to maintain the fine pressure.

  • GU-10:The type of 3/8B caliber, 0.1 ~ 3kPa
  • GU-25:The type of caliber 1B, 0.1 ~ 3kPa

Feature

Most suited for dust proofing of storage tanks for pure water and other substances liable to be degraded by the entrance of dust.

Most suited for shutting off active gases from the contents of storage tanks for foodstuffs, medicines, petroleum products, etc., liable to be degraded by contact with air.

Used to seal inert gases in storage tanks for flammables and most suited for prevention of explosion and fire.

PIPE NOMINAL SIZE
PRIMARY
25A(1″) FLANGE TYPE
SECONDRY
50A(2″) FLANGE TYPE(Tank side)
CONTROL PIPE
Rc1/2(Tank side)
PRIMARY PRESSURE
0.1~0.7MPa *1
SET PRESSURE
0.1~3kPa *2

*1Normal control cannot be effected when primary pressure becomes less than 0.1 MPa. In this case, an external pilot control system can be used. Consult us for details.

*2The pressure setting remains constant when primary pressure fluctuates. As the main valve is pilot operated, a completely sealed tank stabilizes when internal pressure becomes about 0.05-0.1 kPa higher than the setting.
