Description
3 way damper valve
Our leadership position in valve manufacturing innovation is demonstrated through the 3-Way Damper Butterfly Valve which combines technical excellence with engineering expertise. The 3 way valve features a precise flow control system that operates in a 3 directional configuration

The 3-way valve operates flawlessly in heavy industries through its stainless steel, carbon steel and duplex steel materials which provide durability and media compatibility for HVAC, water treatment, Flue gas desulfurization and process engineering applications. The valve achieves improved performance through the implementation of advanced sealing technologies.
Three way butterfly valve Materials
The three-way butterfly valve eliminates leak problems through its design. The valve features WCB, CF8 and CF8M materials which create a tight seal while minimizing leakage to maintain system operation.
The 3 way valve operates effectively across a broad range of temperatures. The valve maintains its performance at any temperature through the use of SS420 and SS431 materials for the stem and various body styles.
The valve features multiple flange accommodation options which provide both installation flexibility and convenience. The valve comes with DIN PN10 PN16, JIS 5K 10K and ANSI CLASS 150LB flange options to match your requirements.
The three way butterfly valve provides reliable actuator options through pneumatic actuators (double acting or single acting) and electric actuators (ON-OFF type or adjustable type) for precise control and reliable operation. Select the actuator that matches your system requirements.
