Lithuania Pneumatic vacuum (pressure) ball valve

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.
