Eccentric half ball

Product Name: eccentric half ball
Product Categories：Eccentric half ball
Product Description：
Eccentric half ball is a relatively new type of ball category, it has its own unique structure of some advantages, such as switches without friction, sealing easy to wear, opening and closing small torque. Such actuators can be reduced with the specifications. With multi-turn electric actuators, can be realized on media regulation and tight cut. Widely used in petroleum, chemical, water supply and drainage and other cities demanding cutting conditions.


Eccentric half ball structural characteristics and uses:
Good sealing performance: the end of a spring metal seat sealing surface to ensure adequate pre-jacking force, in the course of the valve sealing surface wear in the valve spring to ensure good sealing performance; And when high media pressure, unbalanced force generated media sphere guarantee seal.
Bottoms type using stem, set back seal structure ensures a reliable seal packing department.
Top-mounted design: Just remove the valve cover to repair or replace parts.
Widely used in dust, particles, high viscosity medium.
