Q41F یک شیر توپی شناور فلنج دار برای عایق کاری یک چهارم دور در لوله کشی صنعتی است.. The ball is held between its seats rather than supported by trunnions; line pressure presses it toward the downstream seat to form the seal.
The cast steel configuration shown below combines a WCB body with PTFE seats. The specification and dimensional table provide the main details for comparing this model with your piping requirements.

Floating Ball Construction
The floating ball moves slightly under line pressure, bringing it into contact with the downstream seat. PTFE seats provide the sealing surfaces around the ball, while the quarter-turn stem connects it to the operator.
Flanged ends allow the valve to be bolted into the pipeline and removed for maintenance. The dimension table below supports installation planning and comparison with existing valves.
