GUQ pneumatic high vacuum ball valve
详情介绍
he product description
Product introduction:
Pneumatic high vacuum ball valve is suitable for connecting or cutting off the medium flow in the vacuum system. This valve is powered by compressed air, through the control of pneumatic components to change the direction of the air road, driving the mechanical transmission of piston rack, gear, angular stroke output torque to drive the ball valve for opening and closing movement. The valve is three-piece and spherical sealed, so it can be used either in vacuum or under low pressure and can be installed in any position. Cylinder is divided into double action and single action (spring return), can be selected with feedback signal device and electrical valve positioner.
Suitable for medium flow of gas or liquid with acid or alkali.
