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 offer various CV values to match system demands. A higher Cv means greater flow capacity. For example, a CV of 50 is needed for a flow rate of 50 gallons per minute to ensure optimal performance.
