Gas solenoid valve VGG Introduction to VGF

The main body is cast iron, with a straight acting diaphragm structure. The diaphragm is perpendicular to the valve body flange, i.e. parallel to the intake direction.

VGG is an internal threaded connection. VGF is a flange connection.

Class A gas valve, used for gas installations. Single level control.

□ Safety cut-off function, in accordance with EN161 standard, using SKP Electric hydraulic actuator control.

□ Applicable to I Control of Class III gases.

□ With SKP The electric hydraulic actuator is connected and can be combined to quickly close and slowly open.

Two way valve, normally closed type.

The VGG size is RP1/2 ", RP3/4", RP1 ", RP1 1/2", RP2 ".

The size of VGF is DN40, DN50, DN65, DN80, DN100, DN125, DN125.

Use SKP Or SKL Actuator control.

application
