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.

GI series high vacuum butterfly valve is used to connect or cut off the air flow in the vacuum tube. The opening and closing of the valve has a locking function. The applicable working medium is air and non-corrosive gas.

GI-A series high vacuum butterfly valve is used to connect or cut off the air flow in the vacuum tube. The valve plate of the valve adopts a clamping structure, which clamps the sealing ring of the valve plate, has the function of fine-tuning the main seal, and the valve opening and closing has a locking function. . The applicable working medium is air and non-corrosive gas.

The pneumatic actuator of GIQ-B series pneumatic high-vacuum butterfly valve is powered by compressed air, changes the direction of the air path through the electromagnetic reversing valve, promotes the mechanical transmission of the piston rack and gear, and drives the butterfly valve with angular stroke output torque. Opening and closing movement. In order to achieve the purpose of connecting or cutting off the air flow in the vacuum pipeline, it is a new type of pneumatic butterfly valve controlled by a pneumatic actuator, which is divided into double-acting and single-acting (spring return) cylinders, and feedback signal devices and electric valve positioning are optional. device. The applicable working medium is air and non-corrosive gas.
