The matches
valves：
|
Solenoid valve
(Model: V15 or V20)
During normal status,
the valve is no power
consumption, energy
saving and high safety.
The pipeline bursts,
boils the overflow,
blows out ... and so on
cause which the gas
leaks, gas alarm output
the 12V pulse signal to
the valve to interrupt
gas.
The pull rod has the
dustproof and waterproof
cover. Meet IP-54.
Could use the manual
control to opens or
closes the valve.
Suits to the pipe size:
1/2" or 3/4" (V15 for
1/2”, V20 for 3/4”)
Working pressure:
500mBAR
Must conjunction the gas
alarm or related
equipment that provide
the signal.
Corresponding alarm
series: ST-700AE,
ST-710AE, and
ST-720AE…(Refer to the
Selection
guide)
|
 |
Mechanical valve
(Model: MV-20N)
During normal status,
the valve is no power
consumption. Suit for
any working pressure.
When the gas
concentration achieved
the threshold, the alarm
provides DC12V to the
mechanical valve,
automatically turns off
the gas, guarantees the
security.
With manual shut-off and
reset button.
Directly installs on the
ball valve. Unnecessary
to cut off the gas
pipeline, installs
conveniently.
The substitution product
of the solenoid valve,
must conjunction the gas
alarm or related
equipment that provide
the signal.
Corresponding alarm
series: ST-700AM,
ST-710AM, and ST-720AM…

For
single station use：If
the supply cord is
damaged, it must be
replaced by the
