Three-Way Plug Valves
What are Three-Way Plug Valves?
Three-Way Plug Valves are multi-port valves used to divert or mix fluid flow in sanitary systems. Designed for dairies and food processing units, they enable switching between multiple pipelines or directing flow with minimal downtime. These valves are known for their precise routing, clean internal structure, and hygienic sealing.
Asiad Steel Industries manufactures and exports a wide range of Three-Way Plug Valves with options for manual or pneumatic operation to suit dairy-grade applications.
Key Features
- Dual-Function Routing – Directs, diverts, or mixes flow between 3 lines.
- Hygienic Construction – Ideal for milk, yogurt, and clean-in-place lines.
- Smooth Operation – Quarter-turn actuation for reliable switching.
- Dead-Leg Free Design – Minimizes fluid retention zones.
- High-Quality Finish – Electro-polished internals for food safety.
Types of Three-Way Plug Valves
- L-Port & T-Port Valve Configuration
- Manual & Pneumatic Operation
- Clamp-End / Weld-End Models
- Food-Grade PTFE Seat Valves

Do you have questions?
What’s the difference between L-Port and T-Port plug valves?
L-Port diverts flow between two outlets; T-Port can mix or distribute flow between three ports simultaneously.
Can I use this valve for mixing applications?
Yes. T-Port versions are suitable for mixing two inlets into one outlet.
Are they safe for food and dairy fluids?
Absolutely. All materials used are FDA-approved and comply with 3A and hygienic design standards.
Do you offer spares or actuator accessories?
Yes. We offer seals, plugs, gaskets, and actuator kits for all models.
