T-port duplex steel three-way ball valves are specially engineered valves whose core component is the sphere, delivering superior fluid control performance. Featuring three connection ports for interfacing with three pipelines, these valves enable fluid redirection and distribution functions.
Core Components
T-port three-way ball valves comprise four essential components:
Valve body: Features a T-configuration with three ports – typically one inlet and two outlets (or two inlets and one outlet)
Sphere: Contains an L-shaped or T-shaped bore; rotation alters fluid flow paths
Seats: Manufactured from wear-resistant materials to ensure sealing integrity
Stem: Connects to the sphere, enabling rotation via manual or electric actuation
Operating Principle
The valve functions through angular positioning of the sphere:
Open flow: When the sphere bore aligns with body ports, fluid passes freely
Flow alteration: 90° rotation closes ports or redirects flow
Functional Modes:
Flow Divergence (L-bore):
Fluid enters through one inlet, then diverts to either outlet via the L-shaped bore
Flow Convergence (T-bore):
Fluid from two inlets merges through the T-bore into a single outlet
Flow Switching:
Rapid flow redirection achieved by sphere rotation, ideal for systems requiring frequent process changes
