Wholesale Z4 Forced Closed Unique Design Structure Orbit Ball Valve in Bulk

Bonnet packing type

Optional in OS&Y (Outside Screw and Yoke) or Injectable Enclosed designs;

Top-entry structure

All internal valve components, such as the valve plug, stem, and seat, can be removed and replaced online by opening the upper bonnet;

Port size

Full port or reduced port options;

Forced sealing

When the valve is closed, the wedge-shaped flat surface at the lower end of the stem provides a mechanical clamping force, pressing the valve plug tightly against the seat to achieve effective forced sealing.

Friction-free rotation throughout operation

During rotation of the valve plug, a small gap exists between the plug and the seat, ensuring no contact or friction throughout the rotation process. This significantly extends the valve's service life, making it suitable for frequent on-off applications;

Low-torque operation

Due to the "friction-free rotation throughout operation" feature, valves of most sizes can be easily operated with a handwheel, except for larger caliber and higher pressure class valves, which are equipped with gearboxes;

Self-cleaning function

When the stem is lifted upward, the valve plug first disengages from the seat, exposing a small gap. At this point, the medium fluid flushes the sealing surface at 360° at high speed and forms a high-velocity vortex at the edge of the seat, removing accumulated debris from the sealing surface and seat;

Valve seats

Based on different operating conditions, three main types of seats are available for customer selection: soft-sealed seats, metal-sealed seats, and Block & Bleed seats. Customized products can also be provided according to special requirements.
