Hiwa Butterfly Valve, Lug Style, are the best choice for 3-Way T Assembly, 

Ductile Iron Body, CF8M Stainless Steel Disc, EPDM Seat,

with Pneumatic Actuator or Electric actuator, 

It is the best choice for 3-way assemblies, Lug style Ductile iron body Butterfly valves with Tee assembly, with actuator,

in systems that require continuous, proportional mixing or diverting of two fluid streams while aiming to maintain a relatively constant total flow rate in the main circuit, typically for precise temperature or concentration control,

It is extensively used in HVAC, industrial process control, and district heating. Its advantages of maintaining constant flow, high control precision, and a compact design make it a critical component in fluid blending and distribution systems.

The core application condition for a three-way control butterfly valve is in systems that require continuous, proportional mixing or diverting of two fluid streams while aiming to maintain a relatively constant total flow rate in the main circuit, typically for precise temperature or concentration control.
