Pneumatic high pressure ball valve PN320 PN500 stainless steel

Detailed Product Introduction

The Q611F series pneumatic high-pressure forged steel ball valve represents a premium solution for automated high-pressure media management. Machined from high-density forged square blocks (including SS304, SS316, and heavy-duty A105), this valve line is structurally optimized to withstand tremendous line pressures rating from PN320 up to PN500 (approx. 4640 to 7250 PSI). The valve is fitted with a rugged ISO 5211 standard mounting bracket connected to a precision-engineered aluminum rack-and-pinion pneumatic actuator. Featuring female threaded inlet and outlet ports, it creates a highly secure, leak-proof mechanical joint. It delivers exceptional performance under rapid, high-cycle automated cutting operations for hydraulic oils, high-pressure gases, water jetting systems, and severe process chemicals.
