CONSTRUCTION AND WORKING PRINCIPLES
The VG series safety solenoid valves
are class A fail safe shutt--off valves.
The valve can be opened manually
after energizing the operator.
The operator consists of a coil and coil
housing. Through this operator moves
a shaft which is connected to the
closing member. On this shaft a disc is
mounted which can be moved towards
the coil by pulling the setting knob and
will be kept in that position when the
operator is energized.
De--energization will cause the spring
loaded closing member to close.
A strainer made out of steel according
to AISI 303 is incorporated in the valve.
Valve closing spring is made out of
steel according to AISI 302.
Seals and gaskets are manufactured
out of hydrocarbon NBR resistant are
according to DIN 3535 and EN 291.
