CC-A Manual Ultra-high Vacuum Gate Valve
CC-A Manual Ultra-high Vacuum Gate Valve Image

CC-A Manual Ultra-high Vacuum Gate Valve uses a handle to drive steel ball shelf ,to perform valve plate open and close action,fold plate by spring force , open then exit. It is used to put through or cut off the air passage in ultrahigh Vacuum system. Applicable medium can be pure air and noncorrosive gases.

CCQA pneumatic ultra-high vacuum gate valve
CCQA pneumatic ultra-high vacuum gate valve Image

CCQ-A pneumatic ultra-high vacuum gate valve takes the compressed air as power, change the direction of air passage by solenoid directional valve, and controls the actuating cylinder to drive the valve plate up and down to make the valve opened or closed. Thus reaches the aim of put through or cut off the air passage in vacuum pipeline. Applicable medium can be pure air and noncorrosive gases.

GDQ pneumatic high vacuum damper valves
GDQ pneumatic high vacuum damper valves Image

GDQ pneumatic high vacuum damper valve(Angle Valve), motivated by compressed air, pushes the cylinder to up and down move with the valve rod by changing the direction of electromagnetism to transform the gas circuit direction, which drives the valve to open or close, in order to cut off or connect gas flow in the Vacuum system. GDQ-J is angle type and GDQ-S is three-way type with prepumping. Applicable medium can be air and noncorrosive gases.

GU series electric vacuum ball valve
GU series electric vacuum ball valve Image

GUD series electric vacuum ball valve is applicable for the medium flow of connecting or cutting off the pipelines in the Vacuum system. The straightway manual valve relies on spherical sealing. It can be used in both the vacuum and low pressure conditions. It can also be installed in random position.
The applicable active medium of this valve are acid, alkali gas or liquid.

D-J(b) manual high vacuum damper valve
D-J(b) manual high vacuum damper valve Image

GD-J(b) manual high vacuum damper valve(Angle Valve) is one of the important components in the Vacuum system. The transmission component is in screw structure, depended on the hand power to revolve the wheel and open or close the valve.Applicable medium can be air and noncorrosive gases.

DDC-JQ series electro-magnetic vacuum gas valve
DDC-JQ series electro-magnetic vacuum gas valve Image

DDC-JQ series electro-magnetic vacuum gas valve is a special valve installed in rotary vane vacuum pump.
The valve and pump should be connected in the same power. The pump start / stop directly controls the valve open / close. When the pump stops working or there is a sudden interruption of the power supply, the valve will automatically close the Vacuum system and fills gas into pump through the pump gas inlet. In this way, it prevents the pump oil return to the Vacuum system.
The applicable active medium of this valve are air, non-corrosive gas.
Note: Quick release and Loose flange connection and outline dimension Please refer to DDC-JQ-B series electro-magnetic vacuum gas valve( including DN100 spec.)

When the pump stops working or there is a sudden interruption of the power supply, the valve will automatically close the Vacuum system and fills gas into pump through the pump gas inlet. In this way, it prevents the pump oil return to the Vacuum system.
The applicable active medium of this valve are air, non-corrosive gas.

DYC-Q series low vacuum electro-magnetic pressure
DYC-Q series low vacuum electro-magnetic pressure Image

DYC-Q series low vacuum electro-magnetic pressure difference valve is a new vacuum valve which has been installed in the gas inlet of the mechanical pump. The working principle is the valve and pump should be connected in the same power . When the pump stops working or power supply is suddenly interrupted, the valve will depend on atmospheric and vacuum pressure on making the valve plate closes automatically, will be closed Vacuum system to maintain their vacuum, and the atmosphere through the throttle valve into the pump chamber in order to avoid pump oil return to Vacuum system. In this way, it protects the Vacuum system and is beneficial for the re-starting of mechanical pump.
The applicable active medium of this valve are air, non-corrosive gas.

GD-J high vacuum damper valve
GD-J high vacuum damper valve Image

GD-J high vacuum damper valve(Angle Valve)is used to open or close the air current in the Vacuum system. The screw drive is adopted as the transmitted components to lift the valve, which are lighter and reliable in movement. GD-J is angle type and GD-S is three-way type with prepumping. Applicable medium can be air and noncorrosive gases.

GDC-J electromagnetic high vacuum damper valve
GDC-J electromagnetic high vacuum damper valve Image

GDC-J electromagnetic high vacuum damper valve is used to open or close the valve by electromagnetic and spring-return force, applying itself to open or cut off the air current within the Vacuum system. It allows to bear the atmospheric pressure over the valve sealed surface while the downside is full of vacuum as the valve is closed. Under such circumstance can the valve be opened regularly after connecting the electrical control power.

GDQ-J(b) electronic and pneumatic high vacuum
GDQ-J(b) electronic and pneumatic high vacuum Image

GDQ-J(b) electronic and pneumatic high vacuum damper valve(Angle Valve) is sealed by sylphon and signaled by electrical signal as the valve switch and depended on the compressed air as the motive force to open or close the valve. The valve will be relied on the spring to close the valve automatically when losing power supply or the compressed air. To be the on and off mechanism in the high vacuum tube, such valve is advantageous in operating steady and reliable with long life span, which can be the top choice within the automatic vacuum facilities. Applicable medium can be air and noncorrosive gases.

GDQ-J(b)-A high vacuum damper valve(Angle Valve)
GDQ-J(b)-A high vacuum damper valve(Angle Valve) Image

GDQ-J(b)-A pneumatic high vacuum damper valve(Angle Valve) is sealed by sylpho. Motivated by compressed air, it pushes the cylinder to up and down move with the valve rod by changing the direction of electromagnetism to transform the gas circuit direction, which drives the valve to open or close, in order to cut off or connect gas flow in the Vacuum system. Such valve is advantageous in operating steady and reliable with long life span, which can be the top choice within the automatic vacuum facilities. Applicable medium can be air and noncorrosive gases.

GI-C series high-vacuum butterfly valve
GI-C series high-vacuum butterfly valve Image

GI-C series high-vacuum butterfly valve can control the airflow in the Vacuum system from 0°to 90°. he applicable active media of this valve are air, non-corrosive gas.

GM High Vacuum Diaphragm Valve
GM High Vacuum Diaphragm Valve Image

GM High vacuum diaphragm valve use valve rod to press rubber film directly on the valve seat, use to cut-off or connect Vacuum system. Connection form as: Lap joint flange connection, fast unload flange connection, weld type connection. Weld type connection is divided into weld I type connection(both end weld), weld II type connection(one end weld, another end insert). Applicable medium can be air and noncorrosive gases.
