Three-Way Control Valve

A Three-Way Control Valve Manufacturer in Canada, Valves Only Canada supplies three-port control valves for mixing and diverting process flows. In mixing service, two inlet streams combine into one outlet. In diverting service, one inlet flow is split between two outlets. The actuator positions the plug to vary the flow area through the ports and regulate flow, pressure or temperature.

Features

• Three-port globe-style body
• Mixing or diverting configuration
• Plug-and-seat throttling
• Linear or equal-percentage characteristics
• Balanced or unbalanced trim
• Cage-guided trim
• Replaceable trim
• Metal or soft seat
• Pneumatic or electric actuation
• PTFE, graphite or low-emission packing
• Flanged, butt-weld or socket-weld ends
• Liquid, gas and steam service
