GU-A series vacuum (pressure) ball valve is suitable for connecting or cutting off the medium flow in the pipeline in the vacuum system. The valve is a straight-through manual ball valve, which is sealed by a spherical surface, so it can be used in both vacuum and low pressure conditions, and can be installed at any position. Applicable working medium is gas or liquid with acid and alkali

GUQ-A series pneumatic vacuum (pressure) ball valve is suitable for connecting or cutting off the medium flow in the pipeline in the vacuum system. The valve is powered by compressed air, changes the direction of the air path by controlling the pneumatic components, pushes the mechanical movement of the piston rack and gear, and drives the ball valve to open and close with angular stroke output torque. The valve is straight-through and sealed by a spherical surface, so it can be used in both vacuum and low pressure conditions, and can be installed in any position. The cylinder is divided into double-acting and single-acting (spring return), optional feedback signal device and electric valve positioner. The applicable working medium is gas or liquid with acid and alkali.

GUD-A series electric vacuum (pressure) ball valve adopts rotary electric and electronic regulating valve driving device, which can realize valve opening and closing by switching external power supply (manual index switch or computer control) or external input signal Or the control of the middle position, so as to achieve the purpose of turning on or cutting off the air flow in the vacuum pipeline. The valve is straight-through and sealed by a spherical surface, so it can be used in both vacuum and low pressure conditions, and can be installed in any position. The applicable working medium is gas or liquid with acid and alkali.

The CCD series electric ultra-high vacuum plug-in valve uses the screw to electrically push the sealing shaft (rod) to move axially and push (pull) the lifting mechanism to drive the driving body to move axially. When the positioning plate moves to the stop block, the sealing The pressure plate and the support plate stop moving axially, and the steel ball lying in the ball socket of the sealing pressure plate and the support plate is pushed out of the ball socket by the driving body, so that the support plate and the sealing pressure plate are away from the driving body and pressed against the supporting surface of the valve flange And the sealing surface, when the steel ball completely leaves the ball socket and is on the plane of the support plate and the sealing pressure plate, the pressing force reaches the maximum, and the valve is completely closed. When the driving body is pulled to move backward, due to the sealing pressure plate and the support plate The friction between the flange surface and the flange surface is very large, the steel ball is pulled back to the ball socket by the driving body, the sealing pressure plate and the support plate are pressed to the driving body under the action of the central spring, and move backward together with the driving body to leave the flange orifice , so that the valve is fully open. The applicable working medium is clean air and non-corrosive gas.
