Structural Design
Three-Piece Structure
Composed of the valve body, left bonnet, and right bonnet, connected by bolts. This structure enables direct on-line inspection and maintenance of the valve installed in the pipeline, effectively reducing equipment downtime and maintenance costs.
Floating Ball Design
Under the action of medium pressure, the ball can generate a certain displacement and press tightly against the sealing surface of the outlet end to ensure outlet-end sealing. It features a simple structure, good sealing performance, and is suitable for medium and low-pressure working conditions.
Stem Design
The stem adopts a special structural design for low torque, allowing the valve to be easily opened and closed with a small handle. The stem typically uses a bottom-mounted structure to prevent it from being ejected when the valve cavity experiences abnormal pressure increase.

Nominal Pressure (PN)	Pressure rating that the valve can withstand	For example, DN15 - PN25 represents a valve with a nominal diameter of 15 mm and a nominal pressure of 2.5 MPa ²
Connection Method	Connection form between the valve and the pipeline	Internal thread (N), external thread (E), etc. For example, "DN15" in Q11F - 16P - DN15 corresponds to the internal thread connection diameter
Material Compatibility	Matching of valve body material with DN15	Valves made of materials such as carbon steel (W) and stainless steel (S) all have the DN15 specification ¹
