Vacuum valve - Ball valve
GUD series electric vacuum ball valve
GUD series electric vacuum ball valve adopts the rotary electric, electronic regulation type valve drive device. It can fulfill the valve open,close or intermediate position control through externally-connected power source conversion (by manual indexing switch or computer control) or outer input signal. It is applicable for connecting or cutting off the airflow in vacuum tubes.
The straightway 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.
