VGDQ-JB series  electronic and pneumatic high vacuum damper valve (angle valve) is turned by a solenoid valve to rely on air power as the opening and closing valve plate in the loss of power or compressed air when the valve diameter DN80 following spring force will rely on self-closing valve door, DN100 and above using one-way valve through the solenoid valve cylinder valve quickly closed the original gas supply pressure to automatically close the valve. Vacuum system to achieve the cut off the flow of the function. 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 non-corrosive gases.

VGDQ-J model for the angle-pass type, VGDQ-S model for the mouth of the links with pre-pumping type. Applicable to the work of the media to air and non-corrosive gases.
