Pneumatic Three-Way Female-Threaded Ball Valve
Three-way female-threaded connections for small and medium pipeline switching systems.
Product overview
The pneumatic three-way female-threaded ball valve covers DN10~DN80 and is rated for 6.4MPa (1000PSI), with threads complying with Chinese and American standards. Various body and seat materials are available. Threaded connections eliminate flanges for convenient installation and compact dimensions. The three-way passage diverts, mixes and switches the medium, allowing one valve to replace several two-way valves, simplify piping and save installation space.
Double-acting and single-acting spring-return pneumatic actuators are available, with automatic return on air loss in the single-acting version and two-position shut-off control. The top mounting pad accepts solenoid valves, limit switches and other automation accessories directly. Smooth passages without dead spaces, fast operation, pressure and impact resistance, and resistance to internal leakage over long service make it widely suitable for multi-stream switching in small automated equipment, water treatment, and oil and gas transport.
