Reliable 3 Way Plug Valve
The 3-Way Plug Valve is a versatile valve that directs fluid through three different pathways, making it ideal for systems needing flexible flow control. Inside the valve, a plug with three ports rotates to control which paths are open or closed.
This allows operators to switch between different flow routes, combine flows, or even shut off flow entirely with one valve. Its design is simple yet efficient, offering reliable flow control for various industrial applications where redirecting fluid is essential.
Quality Control
The PMI test checks the metal used in the 3-way plug valve. It confirms the material matches the required specifications for safety.
PMI Test
The sealing test checks if the valve can stop leaks under pressure. This process guarantees that no fluid escapes during operation.
Sealing Test
The low emission test measures how well the valve controls gas leaks. It helps confirm the valve minimizes harmful emissions effectively.
Low Emission Test
The impact test checks the valve’s ability to withstand sudden hits or pressure. Inspectors observe if the valve stays strong under force.
Impact Test
Dimension inspection confirms that the valve’s parts are the right size and fit perfectly together to function correctly in the system.
Dimension Inspection
The painting thickness test checks if the valve’s paint layer is thick enough to protect it from rust and damage over time.
Painting Thickness Test
PT, or Penetrant Testing, finds any small cracks or flaws on the valve’s surface. This helps to detect problems not visible to the naked eye.

3 Considerations When Buying a 3 Way Plug Valve
01
Port Configuration
Port configuration is essential in matching the valve to your system’s needs. A standard 3 Way Plug Valve has an L or T port, which determines how the flow is directed. Selecting the wrong configuration can disrupt the process flow.
02
Actuation Method
Determine the type of actuation needed for your 3 Way Plug Valve, whether manual, pneumatic, or electric. Electric actuators might cost more upfront but offer precise control, which is essential for complex systems. The wrong actuation method can lead to inefficiencies in your process.
03
Flow Capacity (Cv)
NTVAL’s 3 Way Plug Valves are designed with various flow capacities, or Cv values, to meet different system demands. A valve with a higher Cv allows for greater flow. For example, if your system requires a flow rate of 50 gallons per minute, a valve with a Cv of at least 50 would be necessary to maintain optimal performance.
