Manufactuer: Kaneko Sangyo
Model: GU-10 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

This method suits dust-proofing storage tanks for pure water and other substances prone to degradation by dust. It also effectively shuts off active gases from the contents of storage tanks for foodstuffs, medicines, petroleum products, and more, preventing degradation through contact with air.

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

Standard specification

NOMINAL PIPE SIZE

PRIMARY

Rc3/8

SECONDARY

Rc3/4（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.

*2Fluctuation of primary pressure causes the pressure setting to vary. 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.
