Pneumatic 3PC Female-Threaded Ball Valve
Three-piece female-threaded design for small and medium diameters, with easy disassembly and maintenance.
Product overview
The pneumatic 3PC three-piece female-threaded ball valve covers DN10~DN80, with a pressure rating of 1.6~6.4MPa (1000PSI). Its three-section body is forged from CF8/CF8M stainless steel for corrosion resistance and compact construction. Seat materials are selectable, and female-threaded connections allow convenient installation and removal for small-bore pipeline upgrades. The integral top mounting pad accepts automation accessories directly, enabling efficient integration without an additional adapter bracket.
Double-acting and single-acting spring-return pneumatic actuators are available, with automatic return on air loss in the single-acting version. It provides two-position on/off shut-off control only and is widely used in small fluid pipelines in water treatment, food and beverages, fine chemicals and semiconductors. The three-section split construction simplifies disassembly and maintenance, while responsive opening and closing and stable torque make it a standard shut-off valve for small-bore automated pipelines.
