Pneumatic Three-Way Ball Valve
Pneumatic actuator drives a three-way ball to switch between L-port and T-port flow paths, ideal for flow mixing, diverting, and directional control.
Inquire Now →Product Overview
Pneumatic three-way ball valves feature a single ball with three ports, allowing one valve to perform flow switching, mixing, or diverting functions that would normally require multiple two-way valves. Compressed-air actuation provides fast 90° operation and reliable remote control.
Available in two standard ball configurations — L-port and T-port — to match your piping logic.
L-Port vs. T-Port Flow Paths
The diagram below shows the typical flow combinations for L-port and T-port three-way ball valves. L-port provides direction switching between two outlet ports, while T-port enables mixing, diverting, and straight-through flow.
Key Features
- Two Configurations: L-port for flow direction switching; T-port for mixing, diverting, and straight-through service
- Fast Pneumatic Actuation: 90° open/close in under 2 seconds, supports double-acting and spring-return actuators
- Compact Design: Replaces multiple two-way valves and reduces piping complexity
- Reliable Sealing: PTFE / RPTFE / PPL seats provide bubble-tight shutoff
- Wide Compatibility: Handles water, oil, gas, steam, and mildly corrosive media
