Detailed Product Introduction

The BKH series high-pressure stainless steel ball valve is a premier solution for heavy-duty fluid control in high-pressure hydraulic configurations, fluid sampling pipelines, and critical instrumentation skids. CNC-machined from supreme high-density forged stainless steel square blocks, this valve is structurally reinforced to master working pressures up to 6000 PSI (414 bar) without deformation. Equipped with a heavy-duty stainless steel or zinc-alloy lever handle, it delivers low operating torque and instantaneous quarter-turn positive shut-off. Its straight-through design ensures an unrestricted fluid path, effectively eliminating cavitation and minimizing pressure drop. Proven to operate flawlessly in ambient extremes from -54°C to +150°C, it represents the industrial standard for offshore oil rigs, chemical processing plants, and high-pressure gas distribution utilities.
