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.
