Vacuum Angle Valve
Vacuum angle valve is used for turn on or shut off the airflow in the vacuum pipeline, the applicable media is air and non-corrosive gases.
It has two structures, one is angle type and another is a 3-way type within an ISO-KF or ISO-F various flange end pre-pump port.
a) Small diameter (≤DN50) valve body are precision investment casting.
b) Large diameter (> DN50) valve body are molding shaped seamless steel or steel plate.
c) Bellows sealed structure can withstand 150oCtemperature, metal sealed structure can withstand 450oCtemperature.
d) Can install on any position to control the airflow in the vacuum pipeline, as an on-off valve purpose

Electromagnetic High Vacuum angle Valve
The GDC-J series Electromagnetic High Vacuum angle Valve is a high performance device which can turn on or cut off the vacuum airflow in the vacuum pipeline when by electromagnetic drive. a) With an good control circuit, the temperature from the solenoid coils less than 50°degree; b) A counter-top atmosphere functions; c) Superior performance of a wide range of power supply: low voltage start, low voltage is maintained, for 50Hz / 60Hz power supply can be applied; d) On – off operation time is short than <1 seconds, working frequency is up to 6 times / min; As a on - off control valve using, usually mounted on the control node vacuum path; As an air gas valve using, can shorten the air charging time, usually adopt to automatic control.
