Features of Top Entry Ball Valves

Durable

Top Entry Ball Valves are made of ASTM A479 F316 stainless steel or custom alloy steel, resistant to high pressure and particulate media erosion, with a service life exceeding 5 years.

High Pressure Withstandable

The structural design can withstand PN16-40/ANSI 150-1500 pressure, ensuring stable operation under high pressure conditions.

Easy Maintenance

The top-entry design allows for individual replacement of the valve ball and seat without disassembling the piping, facilitating on-site maintenance.
