API Ball Valve-Yuming Valve Group

INTRODUCTION

Yuming API ball valve complies with API 6D & ASME B16.34 standards, engineered for reliable bubble‑tight shut‑off in demanding industrial piping systems. Available in floating ball design for small‑medium sizes and trunnion‑mounted ball structure for large‑size and high‑pressure working conditions.

This flanged ball valve covers size range from 1/2'' to 24'', pressure class 150LB‑1500LB. Body material options include WCB carbon steel, A105 forged steel, CF8 / CF8M stainless steel and alloy steel. Soft‑seat and metal‑to‑metal hard‑seat versions are optional. Fire‑safe and anti‑static construction is available to satisfy API 607 requirements.

Quarter‑turn 90‑degree operation enables fast opening and closing with low flow resistance. Full‑port and reduced‑port designs are optional. Flange dimensions follow ASME B16.5, face‑to‑face dimension conforms to ASME B16.10. Robust construction delivers long service life and convenient on‑site maintenance.
