Features

The electric actuator drives the stem to rotate a perforated ball (or segmented ball), achieving on/off via 0-90° rotation. Compared with same-spec gate/c Globe valves, ball valves are smaller, lighter and easier for pipeline installation.

Double-sided Spherical Sealing Function

Achieves zero leakage standard rating.

Valve core channel configurations (optional)

Rectangular
V-shaped
O-shaped

Specially designed PTFE seal

Features excellent self-lubrication
Minimizes frictional loss with the ball
Effectively extends product service life

O-type full-bore valve core

Delivers superior shut-off performance.
