Product info
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.
